Baoquan He dfdc6ba957 mm: ioremap: allow ARCH to have its own ioremap method definition 
Architectures can be converted to GENERIC_IOREMAP, to take standard
ioremap_xxx() and iounmap() way.  But some ARCH-es could have specific
handling for ioremap_prot(), ioremap() and iounmap(), than standard
methods.

In oder to convert these ARCH-es to take GENERIC_IOREMAP method, allow
these architecutres to have their own ioremap_prot(), ioremap() and
iounmap() definitions.
