boards: add stub drivers folder for later use
* boards: add stub drivers folder for later use
The board/drivers folder is added for future use.
In this folder we should place drives that are platform specific and
depend on HW that is present only on a specific platform.
NOTE: All shared drivers should go to the regular driver folder

* tools: shift BOARD_DIR one level up
In preparation for drivers and common folders we are moving the
BOARD_DIR path up one level.

* tools: add drivers/platform symlink
Link the boards/<arch>/<chip>/drivers dir to drivers/platform

* drivers: add platform specifc drivers extension
There are platforms that use specific drivers and we should be able to
include those drivers in the build

* board: cxd56xx: drivers: add AK09912 driver for SCU
This is a platform specific driver connected on the SCU unit.

Squashed commit of the following:
boards/arm/s32k1xx/s32k148evb: Correct linker scripts for the S32K148, Update README files, Hook eht S32K148EVB into the configuration and build system.
arm/s32k1xx/s32k148evb: Verify core and peripheral clocking. It is the same as the S32K146EVB. Fixed one-too-many copy-paste error in both.
boards/arm/s32k1xx/s32k148evb: Correct LED and button pin number for the S32K148EVB.
boards/arm/s32k1xx/s32k148evb: Change all occurrences of 146 to 148.
boards/arm/s32k1xx/s32k148evb: Initial S32K148EVB. Initial commit is just clone of S32K146EVB with file name changes
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.
Squashed commit of the following:
s32k1xx/s32k146evb/scripts/flash.ld: Update the linker script for the S32K146.
boards/: Hook the S32K146EVB into the configuration and build system.
s32k146_clockconfig.c: Add S32K146 clock configuration.
boards/arm/s32k1xx/s32k146evb/src/s32k146_periphclocks.c: Update peripheral clocking for the S32K146.
arm/s32k1xx/s32k146evb: Initial support fo S32K146EVB. Starting point is just the S32K118EVB with name changes.
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.
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.
Squashed commit of the following:
boards/arm/s32k1xx/s32k118evb/configs/nsh: Add a basic NSH configuration.
boards/arm/s32k1xx/s32k118evb/scripts: Add linker scripts and Make.defs.
configs/: Hook the S32K118EVB board into the configuration system.
boards/arm/s32k1xx/s32k118evb: Add initial support for the NXP S32K118EVB.
