Currently we allow DRRS on IVB PCH ports, but we're missing a
few programming steps meaning it is guaranteed to not work.
And on HSW DRRS is not supported on anything but port A ever
as only transcoder EDP has the M2/N2 registers (though I'm
not sure if HSW ever has eDP on any other port).
Starting from BDW all transcoders have the dynamically
reprogrammable M/N registers so DRRS could work on any
port.
Stop initializing DRRS on ports where it cannot possibly work.

Frontbuffer rendering will be dropped for modern platforms but
before that we to prepare DRRS for it.
intel_drrs_flush and intel_drrs_invalidate will not be called
for platforms that will not support frontbuffer rendering so DRRS
needs another way to be notified about to page flips so it can change
between high and low refresh rates as needed.

Both functions are pretty much equal, with minor changes that can be
handled by a single parameter.
v3:
- not scheduling work from invalidate operations

It started as a code style fix for the lines above 100 col but it
turned out to simplifications to intel_drrs_set_state().
Now it receives the desired refresh rate type, high or low.

- Fixed the mode refesh rate debug message

We had a mix of intel_edp_drrs_*(), intel_dp_drrs_*() and
intel_dp_set_drrs_state(), so properly renaming all functions to
keep the same pattern.
While at it, also dropping intel_dp_set_drrs_state from the
documentation as it is a static function.
v3:
- dropping documentation style comment in static function
(intel_drrs_set_state)

intel_dp.c is a 5k lines monster, so moving DRRS out of it to reduce
some lines from it.
