sparc32: Fix page_to_phys().
[ Upstream commit 8654164f54bd02787ae91db8526dcae8e7e34eeb ] It doesn't account for phys_base like it should, fix by using page_to_pfn(). While we're here, make virt_to_page() use pfn_to_page() as well, so we consistently use the asm/memory-model.h abstractions instead of open-coding memory model assumptions.
