intel_drrs_compute_config() is 100% DP specific. DRRS on other
types of encoders wouldn't do any of these M2/N2 calculations
etc. So let's move this into intel_dp.c so all the DP state
calculation is more concentrated into one place.

intel_drrs_init() is a mostly pointless wrapper around
intel_panel_add_edid_downclock_mode(), get rid of it.
The only really useful thing left in there is the debug
print regarding the DRRS type supported by the connector.
Let's just move that into intel_panel_init().

Rather than having the connector init get the fixed mode back from
intel_panel and then feed it straight back into intel_panel_init()
let's just make the fixed mode lookup put the mode directly onto
the panel's fixed_modes list. Avoids the pointless round trip and
opens the door for further enhancements to the fixed mode handling.

Rename the DRRS functiosn to say "(de)activate" rather than
"enable/disable". This let's us differentiate between the
logically enabled vs. actually currently active cases.

Let's just do a full DRRS disable/enable across all pipe updates.
This guarantees that the DRRS work doesn't interfere with anything
while the atomic commit is busy reprogramming the pipe.
Needed so that we can start reprogramming M/N seamlessly during
fastsets whenever possible. Also avoids the pre-bdw DRRS PIPECONF
rmw racing with the potential PIPECONF write from the atomic
commit (eg. due to GAMMA_MODE changes).

Ger rid of one more ugly crtc->config usage by storing the DRRS
state under intel_crtc. intel_drrs_enable() copies what it needs
from the crtc state, after which DRRS can be blissfully ignorant
of anything going on around it.
This also lets multiple pipes do DRRS simultanously and entirely
independently.

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.

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.
