Squashed commit of the following:
drivers/lcd/tda19988.c: Numerous changes for a clean compilation.
drivers/lcd/tda19988: Bring in the final pieces from the FreeBSD TDA19988 driver. The driver is now code complete.
drivers/lcd/tda19988.c: Flesh on EDID read logic (still not complete). Add unlink shutdown logic.
drivers/lcd/tda19988.c: Add logic to read one EDID block.
drivers/lcd/tda19988.c: Add tda19988_read_edid() interface. Flesh read() and seek() methods.
drivers/lcd/st7032.c: Fix another error in seek method: Does not account for negative offsets!
drivers/lcd/tda19988.c: Add basic IOCTL infrastructure to support configuratin the video mode. Mostly just a framework for now.
drivers/lcd/tda19988.c: Add more register definitions. Encode page+address in the same was as FreeBSD.
drivers/lcd/tda19988.c: Add support for CEC messaging.
drivers/lcd/tda19988.c: Implement the unlink method. No IOCTLs defined yet.
drivers/lcd/tda19988.c: Add placeholders for missing character driver methods.
drivers/lcd/tda19988.c: Trivial interface improvement to permit reading multiple TDA19988 registers.
drivers/lcd/tda19988.c: Feeble start of TCA19988 drivers. Consists of lower half interface definition and some I2C helper functions. Nothing more.

1. lost data when receiving buffer is full;
2. low-water mask implement issue;
3. re-flush cdc buffer when enabling
4. serial dma is conflict with cdc , modify the serial.h
1. Configurable option to use named config items instead of enumerated ID/Instance numbers.
2. Ability to iterate through the existing configdata items in the /dev/config device.
3. Ability to "unset" a configdata item.
4. Ability to perform "flash_eraseall" on the /dev/config device.
- Avoids the use of up_aesinitialize() entirely, which resolves dependency problems, because this function does not make sure that an actual hardware aes implementation was made available: each SoC is now responsible to ensure the AES hardware is initialized before first use. This applies to lpc43xx, stm32 and sam34.
- Remove definitions of the NEVER used aes_init and aes_update operations. The new AES API will be more suitable.
- Change the unusual naming in stm32 (avoiding possible naming clashes)
- Change the unusual naming in sam34 (avoiding possible naming clashes)
- Add some FAR to pointers and enforce the 80 col limit in stm32 and sam

configs/nucleo-f334r8: add example for the SPWM generation (custom STM32 PWM usage)
arch/arm/src/stm32/stm32_pwm: fix compilation errors if the upper-half PWM logic is not enabled
include/nuttx/drivers/pwm.h: remove dependency on CONFIG_PWM for the upper-half PWM header. This allows compilation for the lower-level PWM drivers even if the upper-half PWM logic is not used.
arch/arm/src/stm32/stm32_tim.c: fix compilation error if there is no TIM8
configs/nucleo-f334r8/highpri: remove the upper-half ADC from configuration
configs/nucleo-f302r8/highpri: remove the upper-half ADC from configuration
configs/stm32f429i-disco/highpri: remove the upper-half ADC from configuration

fs/procfs/fs_procfsproc: Extended the process ID ProcFS output to show per-thread maximum time for pre-emption disabled and maximum time within a critical section.
sched/sched/sched_critmonitor.c: Adds data collection logic in support of monitoring critical sections and pre-emption state.
The user of this invalidation are mmcsd_sdio currently. The mmcsd_sdio driver makes calls for dcache invalidation through the chip specific architecture function SDIO_DMARECVSETUP(). I changed the arch/arm/stm32f7 chips to use arch_invalidate_dcache_by_addr() instead of arch_invalidate_dcache().
This commit includes additional changes to mmcsd_sdio.c. I created SDIO_DMADELYDINVLDT() (DMA delayed invalidate) to invalidate store-into mode dcaches after the DMA transfer. I have been using SDIO_DMADELYDINVLDT() for several weeks now and it has fixed the problems that I previously reported regarding non-cache aligned buffer invalidation errors (for my store-through dcache). However, it does not permit use of unaligned DMA buffers for store-into mode dcaches.
SDIO_DMADELYDINVLDT() is a NoOp unless the chip specific Kconfig file selects CONFIG_ARCH_HAVE_SDIO_DELAYED_INVLDT. I have modified all the stm32f7 chips to select it.
