fbdev: Include <linux/fb.h> instead of <asm/fb.h>

Replace include statements for <asm/fb.h> with <linux/fb.h>. Fixes
the coding style: if a header is available in asm/ and linux/, it
is preferable to include the header from linux/. This only affects
a few source files, most of which already include <linux/fb.h>.
