Imre Deak 738c05c07d drm/i915: vlv: fix cdclk setting during modeset while suspended
Currently after doing DPMS-OFF on all outputs CDCLK won't be set to its
minimum value as it should. A subsequent modeset to turn off all outputs
will thus run with all power domains disabled, and notice that it needs
to change CDCLK to its minimum value. Since the power domains are
disabled this will emit a register-access-while-suspended WARN and fail
to set the minimum freq.

The proper solution for this is to set the minimum frequency during
DPMS-OFF. That needs a bigger rework that would take into account the
user DPMS setting too during the calculation of the new modesetting
configuration. Until that's done this stop-gap solution gets the PIPE-A
power domain during setting the CDCLK; this domain covers the HW blocks
needed for this.

Idea to use PIPE-A domain from Ville.

Testcase: igt/pm_rpm
