drm/i915: Add crtc .crtc_get_shared_dpll()
...
Start splitting the .compute_crtc_clock() into two parts; one
part does the computation, the second part does the shared dpll
assignment. I want to move the actual computation part much earlier
into the compute_config() phase.
v2: dg2_crtc_get_shared_dpll() not needed (Jani)

drm/i915: Adjust .crtc_compute_clock() calling convention
...
Pass the full atomic state+crtc rather than the redundant
crtc+crtc_state pair. We already need the full atomic state
in the hsw+ codepath anyway.

drm/i915: Call {vlv,chv}_prepare_pll() from {vlv,chv}_enable_pll()
...
We always call the vlv/chv prepare_pll() just before enable_pll().
Move the calls into the enable_pll() funcs. We can also
consolidate the DPLL_VCO_ENABLE checks while at it.

Stop passing both the crtc and its state to the DPLL functions.

This pulls a large chunk of the pll calculation code out of
intel_display.c to a new file.
One function makes sense to be an inline, otherwise this
is pretty much a straight copy cover. Also all the
remaining hooks for g45 and older end up the same now.
