stm32f429i-disco: Add support for initializing ltdc framebuffer and the configured lcd display
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 Signed-off-by: Marco Krahl <ocram.lhark@gmail.com>
