stm32_pwm: remove some impossible PWM configurations
stm32_pwm: support for complementary outputs
stm32_pwm: deadtime configuration
stm32_pwm: output polarity and IDLE state configuration
nucleo-f302r8: pwm support

arch/arm: Remove support for CONFIG_ARMV7M_CMNVECTOR. It is now the only vector support available. Also remove CONFIG_HAVE_CMNVECTOR. That no longer signifies anything."
arch/arm/src/stm32: This commit removes support for the dedicated vector handling from the STM32 architecture support. Only common vectors are now supported.
LTDC fixes

* stm32_ltdc: Checks for register reload is done before continued

* stm32f429i-disco: Fixes eliminated register control by compiler optimization
When reading 1 byte from the SPI device the clock must be enabled and
immediately disabled. This section has been optimized by the compiler (-O2) to a
missing active spi clock. A subsequently block read failed because of missing
response from the spi device. This has been lead to a broken display
initializing.

sched/: Convert legitimate uses of task_create() to nxtask_create(). Review handling of returned values from all uses of kthread_create() (as well as nxtask_create()).
graphics/: Review return values for all calls to kthread_start() because it no longer returns an errno.
drivers/: threads started by drivers should be kernel threads, not user tasks. Review return values for all calls to kthread_start() because it no longer returns an errno.
configs/: threads started by board bringup logic should be kernel threads, not user tasksi (part 2 of 2).
sched/task: Add nxtask_create(). Kthread_create() and nxtask_create() are internal OS functions and should not modify the errno variable. configs/: threads started by board bringup logic should be kernel threads, not user tasks.
Squashed commit of the following:
configs: Each board now initializes the touchscreen controller as a normal part of its board bring-up. board_tsc_setup() is gone; the touchscreen controller is now treated like any other on-board device.
Remove all support for BOARDIOC_TSCTEST_SETUP
Move prototype for board_tsc_setup() from include/nuttx/board.h to individual board header files.
configs/stm32f429i-disco/ltdc: This configuration has been deleted because it violated the portable POSIX OS interface. It used apps/examples/ltdc and include ltdc.h and dma2d.h which were also removed for the same reason.
configs/z80sim and xtrs: Serial driver lower halfs ioctl methods should return a negated errno value, not set the errno variable.
drivers/wireless: CC1101 driver not permitted to set errno.
drivers/sensors: LIS331DL driver not permitted to set errno.
drivers/lcd: ILI9341 initialize method not permitted to set errno,
drivers/serial: 16550 UART driver IOCTL method must not set errno; it must return a negated errno value.
