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.

SAMDL DMA fixes and experimental SPI support
* SAMDL: Fix DMA controller support

disable LPC17 FDR when not used (second fix)
if a boot loader sets the fractional divider (FDR) the baud rate in
nuttx will be wrong (multiplied by this fraction).
This also has to be added to lpc17_lowputc.c
Unfortunately the constant used for shifting the bits was wrong in the header file, so it took some time to realize this...
