powerpc: Implement and use pgprot_nx()
ioremap_page_range() calls pgprot_nx() vmap() and vmap_pfn()
clear execute permission by calling pgprot_nx().
When pgprot_nx() is not defined it falls back to a nop.
Implement it for powerpc then use it in early_ioremap_range().
Then the call to pte_exprotect() can be removed from ioremap_prot().
