arch/kmap: define kmap_atomic_prot() for all arch's

To support kmap_atomic_prot(), all architectures need to support
protections passed to their kmap_atomic_high() function.  Pass protections
into kmap_atomic_high() and change the name to kmap_atomic_high_prot() to
match.

Then define kmap_atomic_prot() as a core function which calls
kmap_atomic_high_prot() when needed.

Finally, redefine kmap_atomic() as a wrapper of kmap_atomic_prot() with
the default kmap_prot exported by the architectures.
