drm/i915: Invariably invalidate before ctx switch
We have been setting the bit which was originally BIOS dependent since:
commit f05bb0c7b624252a5e768287e340e8e45df96e42

drm/i915: GFX_MODE Flush TLB Invalidate Mode must be '1' for scanline waits
Therefore, we do not need to try to figure it out dynamically and we can
just always invalidate the TLBs.
It's a partial revert of:

drm/i915: possibly invalidate TLB before context switch
The original commit attempted to only invalidate when necessary
(very much a relic from the old days). Now, we can just always invalidate.
I guess the old TODO still exists. Since we seem to have abandoned ILK
contexts however, there isn't much point in even remembering.
