MIPS: add kmap_noncoherent to wire a cached non-coherent TLB entry
This is identical to kmap_coherent apart from the cache coherency attribute used for the TLB entry, so kmap_coherent is abstracted to kmap_prot which is then called for both kmap_coherent & kmap_noncoherent. This will be used by a subsequent patch. Suggested-by: Leonid Yegoshin <leonid.yegoshin@imgtec.com> Signed-off-by: Paul Burton <paul.burton@imgtec.com>
