The current lcd_display_bitmap() function does not work properly
for the Atmel LCD controller.
2 fixes need to be done:-
(a) when setting the colour map, use the lcd_setcolreg() function
as provided by the Atmel driver
(b) the data is never actually written to the lcd framebuffer !!
Below is a patch to fix these issues.
