Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution: Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly. This commit is for all USB host drivers under arch/.

Call xxx_timer_initialize from clock subsystem to make timer ready for use as soon as possiblei and revert the workaround:

Revert "sched/clock/clock_initialize.c: clock_inittime() needs to be done with CONFIG_SCHED_TICKLESS and clock_initialize should skip clock_inittime() for external RTC case since the RTC isn't ready yet."
This reverts commit 2bc709d4b9.
Commit 2bc709d4b9 was intended to handle the case where up_timer_gettime may not start from zero case. However, this change has the side-effect of breaking every implementation of tickless mode: After this change the tickless timer structures are used before they are initialized in clock_inittime(). Initialization happens later when up_initialize is called() when arm_timer_initialize().
Since the tickless mode timer is very special, one solution might be to
1. Rename xxx_timer_initialize to up_timer_initialize
2 Move up_timer_initialize to include/nuttx/arch.h
3. Call it from clock subsystem instead up_initialize
Basically, this change make timer initialization almost same as rtc initialization(up_rtc_initialize).
For now, however, we just need to revert the change.
* S32K add support for Nxp drone boards
* Update arch/arm/src/s32k1xx/hardware/s32k1xx_rtc.h codestyle

* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

Ran nxstyle against many of the affected files. But this job was too big for today. Many of the network drivers under arch are highly non-compiant and generate many, many faults from nxstyle. Those will have to be visited again another day.

This effects all network drivers as well as timing related portions of net/: devif_poll_tcp_timer shouldn't be skipped in the multiple card case. devif_timer will be called multiple time in one period if the multiple card exist, the elapsed time calculated for the first callback is right, but the flowing callback in the same period is wrong(very short) because the global variable g_polltimer is used in the calculation. So let's pass the delay time to devif_timer and remove g_polltimer.
Squashed commit of the following:
arch/arm/src/s32k1xx: Update peripheral input clocking for the way that things are done for the S32K1XX. Fix other misc. compilation/configuration issues.
arch/arm/src/s32k1xx: Clean up LPSPI and LPI2C naming for S32K1XX. Using S32K1XX clock functions to get peripheral input clock.
arch/arm/src/s32k1xx: Clone i.MXRT LPSPI and LPI2C support. i.MXRT uses the same IP as S32K1XX.
arch/arm/src/s32k1xx/s32k1xx_lowputc.c: Fix a typo that prevented LPUART1 from working.
arch/arm/src/s32k1xx/s32k1xx_periphclocks.c and related files: Fix yet another case of confusion between pre-decremented and non-decremented divider values. Enforce the rule that dividers are not decremented until the moment they are written into registers.
arch/arm/src/s32k1xx/s32k1xx_clockconfig.c: Fix another problem related to whether a divider is pre-decremented or not. The answer must be the divder values are never pre-decremented. They are decremented just before being written to hardware.
arch/arm/src/s32k1xx/s32k1xx_clockconfig.c: Clean up some bad conditional logic. Precedence of operators problem.
boards/arm/s32k1xx/s32k118evb: Add support for execution out of SRAM. This is helpful for bringup when you want to avoid putting a lethal image in FLASH.
arch/arm/src/s32k1xx/s32k1xx_clockconfig.h: Remove crystal frequency, it is not used.
arch/arm/src/s32k1xx/s32k1xx_wdog.h: Fix a typo in a register name.i
boards/arm/s32k1xx/s32k*evb/configs/nsh/defconfig: Create Motorola SREC output format.
boards/arm/s32k1xx/s32k118evb/include/board.h: Add LPUART0 pin disambiguation.
arch/arm/src/s32k1xx/hardware: Add pin mux definitions for S32K116, 118, 142, 144, 146, and 148.
arch/arm/src/s32k1xx/s32k1xx_pin.c and .h: Add support for PIDR register that disables a gneral purpose pin from acting as an input.
arch/arm/src/s32k1xx/s32k1xx_pin.c and .h: The device does not support slew rate controls or open drain (on all the pins). Only pins that are configured for a protocol that requires open-drain (e.g;, LPI2C, LPUART single-wire) will work in open-drain mode.
arch/arm/src/s32k1xx/: Add logic to look up the peripheral clock frequency. Fix baud calcuation logic in s32k1xx_lowputc.c: In no longer tries to enable clocking. That must be done with board logic. Now gets the peripheral functional clock frequency to determine the baud rate.
arch/arm/src/s32k1xx: Add peripheral feature arrays.
Finishes peripheral clock initialization:
arch/arm/src/s32k1xx/s32k11x/s32k11x_clockmapping.c
arch/arm/src/s32k1xx/s32k14x/s32k14x_clockmapping.c
Provide MCU-specific mapping of clock names to PCC control registers.
boards/arm/s32k1xx/s32k118evb/src/s32k118_periphclocks.c
Provides initial clocking for for the S32K118EVB
arch/arm/src/s32k1xx/s32k1xx_periphclocks.c: Add logic to initialize peripheral clocking.
arch/arm/src/s32k1xx/s32k1xx_clockconfig.c: Add SIM clock configuration.
