- Use ptpgzone zone to allocate page table pages irrespective of the amount of
  memory on a platform. Tested on the Sibyte with 256MB and 1GB memory
  configurations.

- Replace vtophys() with MIPS_KSEG0_TO_PHYS() to convert a page table
  page's virtual address to physical. We can safely do this because
  page table pages are allocated out of KSEG0.

- Add an assertion to verify that when a page table page is freed it
  contains all zeroes. We can now use it after allocation without
  zeroing it.
