hw/display/artist: Refactor x/y coordination extraction ...
Simplify the code by using new introduced ADDR_TO_Y() and ADDR_TO_X()
macros. Those macros extract the x/y-coordinate from the given uint32.
As further simplification the extraction of the x/y coordinates for
VRAM_WRITE_INCR_Y and VRAM_WRITE_INCR_X can be done centrally in
vram_bit_write(), so move this code up into the function.
ADDR_TO_Y() is still limited to 10 bits which allow to address up to of
1024 lines - this will be increased in a follow-up patch.
