stm32f429i-disco: change ltdc initializing during boot up. This moves initializing of the ili9341 lcd and ltdc driver to the board specific initializing routine.

STM32F429i-Disco USB:  Strangeness: Conditioned on OTGHS but called otgfs initialize routines.  Must be something broken

Tiva SSI: Fix some recent breakage to the Tiva SSI driver for the case where only one SSI modules is enabled

Tiva SSI and board configurations: hange negative Tiva logic CONFIG_SSIx_DISABLE to positive logic CONFIG_TIVA_SSIx.  Add support for SSI2 and SSI3

Tiva:  Add a configuration setting to better distinguish TM4C123 and 129 families.  Reanem tm4c_syscontrol.h to tm4c123_syscontrol.h; rename tm4c129x_syscontrol.h to tm4c129_syscontrol.h

STM32 LTDC: Move ltdc.h from include/nuttx/video to arch/arm/include/stm32; Trivial updates after general review

Memory configuration:

The heap start address of memory region 3 starts at 0xD0000000.
The allocated framebuffer of the layers is addressed up to the end of the memory
region 3.

If the layer pixel format changes e.g. from RGB565 to RGB24, than the memory
configuration must be configured too. Currently an easy memory calculation
is missing for that in Kconfig.

This adds support for initializing of the ltdc controller and the lcd device connected on the stm32f429i-disco. The following methods are provided for the generic fb interface:

- up_fbinitialize
- up_fbgetvplane
- fb_uninitialize

The following methods are provided for the ltdc interface:

- up_ltdcgetlayer

stm32f429i-disco: update board definition for the ili9341 LCD display. This configures all LCD settings for the RGB interface. Also adds a customer LCD display template.
