Change the pmap_zero_page and pmap_copy_page API to take the struct vm_page *
instead of the pa. Most callers already had it handy and those who didn't
only called it for managed pages and were outside time-critical code.
This will allow us to make those functions clean and fast on sparc and
sparc64 letting us to avoid unnecessary cache flushes.
