[PATCH 3/4] arch/powerpc: Call internal __phys_mem_access_prot() in fbdev code

[Thomas Zimmermann]

Call __phys_mem_access_prot() from the fbdev mmap helper fb_pgprotect().
Allows us to avoid the file argument, which can then be removed from
fB_pgprotect() entirely. No other architecture uses the parameter.
