arch/parisc: Implement <asm/fb.h> with generic helpers 



Replace the architecture's fbdev helpers with the generic ones
from <asm-generic/fb.h>. On PARISC, pgprot_writecombine() and
pgprot_noncached() are the same; hence no functional changes.

v3:
	* use default implementation for fb_pgprotect() (Arnd)
