drm/i915: add media well to VLV force wake routines v2

Browse source

We could split this out into a separate routine at some point as an
optimization.

v2: use FORCEWAKE_KERNEL (Ville)

Note: Ville mentioned in his review that he declines to be responsible
if this blows up due to the lack of "readback a register != FW_ACK,
but from the same cacheline" magic we have in other forcewake
implementations.

[danvet: Bikeshed overtly long lines according to checkpatch.pl. Nope,

those alone.]
