hw/display/pxa2xx_lcd: Remove dead code for non-32-bpp surfaces 

For a long time now the UI layer has guaranteed that the console
surface is always 32 bits per pixel.  Remove the legacy dead code
from the pxa2xx_lcd display device which was handling the possibility
that the console surface was some other format.
