This should probably be ioremap_wc. Otherwise it will be *really* slow
if used in legacy mode and it may cause conflicts with the
pgprot_writecombine mode for mmap.

(Watching boot messages go by on fbcon on efifb was like using an old
2400 baud modem before I made the corresponding change to efifb.)
