Missing BMP 565RGB video support

Hi Agust,

The latest version of the U-Boot does not support conversion from 24BPP BMP to a 16BPP 565RGB encoded frame buffer. It uses always 555RGB encoding (see function video_bmp_display in video_bmp.c). Older versions of the U-Boot (e.g. 2015.04) supported this because the platform specific device driver passed not only the BPP but also the encoding.

Do you know whether this lost support was done on purpose or lost by accident?

I encountered this issue when trying to display a 24BPP BMP splash screen at an i.MX6 platform.
