Subject: [PATCH 3/3] Stop using mos_bo_subdata

This maps to the kernel's PWRITE ioctl but there's no real advantage in
using it since the first thing the kernel does is i915_gem_object_wait().
We may as well do the wait in userspace and just write to it through a
map.  We're attempting to remove PWRITE support from i915 for future
platforms and this prepares the media driver for the move.
