[PATCH] powerpc: replace page_to_virt() with lowmem_page_address() for Book-E

page_to_virt and lowmem_page_address provided equiavlent functionality
so use the more standard lowmem_page_address

This also addresses build issue in ARCH=powerpc since page_to_virt()
has been removed from include/asm-powerpc/page.h
