Intel GPU patch 13.0 for stable/9

[Meowthink]

Hello all,

Here's Intel GPU patch 13.0 for stable/9:

https://docs.google.com/open?id=0BxbPi2OX4_B-NWY3NWU3MzEtNDBjYy00NTljLThlZGItMWFlYjIyYjI4Yjk3

Recently, the patch against stable/9 became very similar to kib's
original patch, which is against current, since kib's device_pager &
mdf's bool/true/false patches are MFCed to stable/9. When making this
one, the only 2 rejects are at:
1. sys/dev/drm/i915_suspend.c of which reason is explained on freebsd's wiki
2. sys/vm/vm_phys.h due to r226928[1] not MFCed(but didn't influence
the patch to work until now).

... but warning: This is NOT for releng/9.0, as it is released before
those MFCs.

Cheers,
Meowthink
