Refactor fb_pgprotect() in PowerPC to work without struct file. Then clean up and rename fb_pgprotect(). This change has been discussed at [1] in the context of refactoring fbdev's mmap code. The first three patches adapt PowerPC's internal interfaces to provide a phys_mem_access_prot() that works without struct file. Neither the architecture code or fbdev helpers need the parameter. Patch 4 replaces fbdev's fb_pgprotect() with fb_pgprot_device() on all architectures. The new helper with its stream-lined interface enables more refactoring within fbdev's mmap implementation.
