sh: Stub out legacy PCC pgprot encoding for X2 TLBs.
Presently it's still possible to reference the PAGE_KERNEL_PCC pgprot encoding on X2 TLBs which simply don't support it at all. Convert this over to follow the nommu behaviour and simply hand back an invalid pgprot value so we error out properly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
