video: da8xx-fb: fix 24bpp raster configuration

Based on original patch by: Manjunathappa, Prakash <[email protected]>
and Afzal Mohammed <[email protected]>

Set only LCD_V2_TFT_24BPP_MODE bit for 24bpp and LCD_V2_TFT_24BPP_UNPACK bit along with LCD_V2_TFT_24BPP_MODE for 32bpp configuration.

Patch is tested on am335x-evm for 24bpp and da850-evm for 16bpp configurations.

v2: removes confusing fall through in case statement for pixel
depth configuration.
