[Intel-gfx] [PATCH 00/19] ddi: respin of runtime PM for DPMS

[Imre Deak]

This is a respin of the unmerged part of Daniel's runtime PM for DPMS
patchset [1]. The original one also included a refactoring of the DDI
PCH/CRT encoder modesetting path, I left the corresponding patches out
from this series. This is because there hasn't been yet an agreement on
those parts, but people would like to see the RPM DPMS support already
applied.

Some patches needed to be updated/rebased because of the above omission,
but these weren't anywhere significant so I just marked the fact
with my s-o-b line. I also added two minor change to keep the
modeset sequence at its current order and collected all the reviewed-by
lines.

Tested on HSW DP/VGA, with basic DPMS on/off and igt/pm_rpm.
