* arch/arm/src/lc823450: Fix up_enable_irq() timing for I2S.
In previous commit, I2S IRQ might be sometimes assigned to CPU1
when CONFIG_SMP=y. This change fixes this issue.

* arch/arm/src/lc823450: Refactor timer driver.
Introduce lc823450_timer.h and move lc823450_timerisr.c to
lc823450_timer.c Add MTM timer APIs for DVFS. Introduce
up_rtc_gettime() for CONFIG_RTC_HIRES.

* arch/arm/src/lc823450: Introduce idle time calculation in DVFS
Also, DVFS autonomous mode based on CPU idle time is supported.
NOTE: voltage control is still disabled.

* configs/lc823450-xgevk: Update defconfigs
Enable RTC_HIRES instead of RTC_DATETIME (audio/rndis)
Disable TCP_WRITE_BUFFERS and change SCHED_LPWORKPRIORITY (rndis)

drivers/mtd: mtd_config.c: Add still more error handling (to detect bad underlying flash implementations)
drivers/mtd: mtd_config.c: Remove MTD_ERASE that was erasing data block instead of erase block. This is a partial revert of 4f18b4. Reported-by: Pascal Speck <iktek01@yahoo.com>
arch/arm/src/stm32l4: stm32l4_flash: change flash programming to use page buffer for unaligned writes.
drivers/lcd and include/nuttx/lcd: Add FT80x support for writing to graphics memory. Also add some definitions needed by apps/examples/ft80x for bitmap manipulation.
drivers/lcd: Review/update FT80x initializatin logic
drivers/lcd: Rename ft80x_base.c to just ft80x.c. Add logic to notify FT80X clients of events via signals.
drivers/lcd: Trivial updates to naming. Add some new definitions.
is not done or done after PLL configuration, the STM32 fail to continue boot
operation if the frequency if greater than 24MHz. This common t add this operation according to the board variable STM32_SYSCLK_FREQUENCY. Tested on stm32f334-disco board.
Squashed commit of the following:
drivers/lcd: Finishes off basic FT80X. Still missing some niceties.
drivers/lcd: Rethink FT80X display list interface.
drivers/lcd: More FT800x display list logic. Still not complete.
drivers/lcd: Add some basic FT80x initialization logic.
drivers/lcd: Add ft80x display list IOCTL framework. Still missing low level display list operations.
drivers/lcd: FT80x driver cannot be a standard LCD driver but must, instead, be a custom character driver.
drivers/lcd: Add FT800 co-processor commands and display list helpers.
drivers/lcd: Add SPI interface and framework for the initialization and the basic LCD driver.
drivers/lcd: Add beginnings of some FT80x implementation.
drivers/lcd: Add definitions for the FTDI FT801 part
include/nuttx/lcd/ft800.h: Add initial FT800 interface definition.
drivers/lcd: Add ft800 header file.
lc823450 smp test
* sched/clock: Replace critical section APIs with spin lock APIs in clock_gettime.c
This change will improve performance for SMP systems but nothing
changes for non-SMP systems. (Pls see include/nuttx/irq.h)

* sched/sched: Remove unnecessary DEBUGASSERT in sched_removereadytorun.c
In SMP mode, rtrtcb is not always at the g_readytorun.head.
This change removes DEBUGASSERT() to avoid this condition.

Fix signal handing for smp
* sched/signal: Remove SMP related logic in sig_dispatch.c
This change prevents from a deadlock in up_schedulesigaction.c
where inter-CPU signal handling is actually implemented.

* arch/arm/src/armv7-m: Fix signal handling for SMP
In previous implementation, signal handling for SMP was incorrect.
Thus, for example, if an inter-CPU signal happened an incorret tcb
was signaled and caused ASSERT().
This change fixes the issues and works for both inter-CPU signal
handling and signal handling on the same CPU.
