[PATCH 12/23] video: da8xx-fb: fix 24bpp raster configuration

[Darren Etheridge]

From: Manjunathappa, Prakash <prakash.pm@ti.com>

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.

I'd suggest not to use fall-through here. It just makes the code more
difficult to read and more error prone.
