Gregory Nutt e63730e995 stm32f429i-disco: add default platform configuration to test framebuffer support for the ltdc 
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.

STM32F429I-DISCO LTDC Framebuffer demo example

Configure and build
-----------------------------------------------
cd tools
./configure -a <appdir> stm32f429i-disco/ltdc
cd ..
make

Loading
-----------------------------------------------
st-flash write nuttx.bin 0x8000000

Executing
-----------------------------------------------
The ltdc is initialized during boot up.
Interaction with NSH is via the serial console at 115200 8N1 baud.
From the nsh comandline execute one (or both) of the examples:
- nx (default nx example)
- ltdc (trivial ltdc interface test)
