[PATCH] vm: convert users of remap_page_range() under include/asm-*/ to use remap_pfn_range()

This patch converts uses of remap_page_range() via io_remap_page_range() in
include/asm-*/ to use remap_pfn_range().  io_remap_page_range() has a similar
physical address overflow issue that needs to be addressed later.
