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.
