Convert remaining memframe LCDs that can be convert to common code.

Massage the way it interfaces a bit to make things more flexible.
The chroma_buf scheme on Sansa Connect and Creative ZVx calling the
lcd_write_yuv420_lines implementation in lcd-as-memframe.S with five params
with a chroma buffer that the function can't use wouldn't work anyway so just
have them use the stock implementation (really, how was that working?).
