Subject: fbdev: xoffset, yoffset and yres are unsigned

The xoffset, yoffset and yres members of fb_var_screeninfo are __u32.
Make them unsigned in the code as well.

Subject: video/fb: cleanup FB_MAJOR usage

Currently, linux/major.h defines a GRAPHDEV_MAJOR (29) that nobody uses,
and linux/fb.h defines the real FB_MAJOR (also 29), that only fbmem.c
needs.  Drop GRAPHDEV_MAJOR from major.h, move FB_MAJOR definition from
fb.h to major.h, and fix fbmem.c to use major.h's definition.
