From: Ben Widawsky <benjamin.widawsky@intel.com>

Now that we don't need to trace num_pd_pages, we may as well kill all
need for the PPGTT structure in the alloc_pagedirs. This is very useful
for when we move to 48b addressing, and the PDP isn't the root of the
page table structure.

The param is replaced with drm_device, which is an unavoidable wart
throughout the series. (in other words, not extra flagrant).
