[Intel-gfx] [PATCH 00/18] Introduce the Haswell VECS v2

The primary change in this series is I introduce the
ivybridge_preinstall and "Add PM regs to pre/post install"
before make "PM interrupt writes non-destructive". This helps address
the issue Damien caught where the PMIMR is never cleared midway through
the series. On that note, I fixed a bug introduced on the previous
rebase where the PMIMR wasn't getting cleared without VEBOX. That fix is
addressed in v2 of "vebox interrupt get/put"

I've also rebased this series on the latest -nightly, and tried to fix
all comments Damien made in the series.

Thanks again to Damien for the review this far.
