[PATCH] mbxfb: Fix framebuffer size smaller than requested
This patch fixes a bug where we obtain a smaller resolution than requested.
(eg: in 640x480, only 639x479 usable pixels).
This was due to 1 being substracted from the xres and yres vars two times:
first in mbxfb.c and then in the macros from reg_bits.h.
This patch removes the minus ones from the mbxfb.c file. Tested and works.
