fbdev: Replace fb_pgprotect() with pgprot_framebuffer()
Rename the fbdev mmap helper fb_pgprotect() to pgprot_framebuffer().
The helper sets VMA page-access flags for framebuffers in device I/O
memory.
Also clean up the helper's parameters and return value. Instead of
the VMA instance, pass the individial parameters separately: existing
page-access flags, the VMAs start and end addresses and the offset
in the underlying device memory rsp file. Return the new page-access
flags. These changes align pgprot_framebuffer() with other pgprot_()
functions.
v4:
* fix commit message (Christophe)
v3:
* rename fb_pgprotect() to pgprot_framebuffer() (Arnd)
