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

initializing
As long as the method up_spiinitialize recognized the initialized state of the
spi device by the spi enable flag of the cr1 register, it isn't safe to disable
the spi device outside of the nuttx spi interface structure. But this has to be
done as long as the nuttx spi interface doesn't support bidirectional data
transfer for multiple devices share one spi bus. This wrapper store the
initialized state of the spi device after the first initializing and should be
used by each driver who shares the spi5 bus.
Note! Understand this as temporary workaround.

This enables the initializing of the lcd device connected on the
stm32f429i-disco. The following methods are provided:
- up_lcdinitialize
- up_lcduninitialize
- up_lcdgetdev
The corresponding ili9341 lcd device in the nuttx driver section can be
configured by Kconfig. Interface 0 is used by default.
