Clean up and rename fb_pgprotect() to work without struct file. Then
refactor the implementation for PowerPC. This change has been discussed
at [1] in the context of refactoring fbdev's mmap code.

The first two patches update fbdev and replace fbdev's fb_pgprotect()
with pgprot_framebuffer() on all architectures. The new helper's stream-
lined interface enables more refactoring within fbdev's mmap
implementation.

Patches 3 to 5 adapt PowerPC's internal interfaces to provide
phys_mem_access_prot() that works without struct file. Neither the
architecture code or fbdev helpers need the parameter.

v4:
	* fix commit message (Christophe)
v3:
	* rename fb_pgrotect() to pgprot_framebuffer() (Arnd)

I had another look today, and everything look good to me now.
