x86: unify kmap_atomic_pfn() and iomap_atomic_prot_pfn(), fix
Impact: build fix
Move kmap_atomic_prot_pfn() to iomap_32.c. It is used on all 32-bit
kernels, while highmem_32.c is only built on highmem kernels.
( Note: the debug_kmap_atomic_prot() check is removed for now, that
problem is handled via another patch. )
