struct intel_dpll_hw_state has a spot for all possible
PLL registers across all platforms (well, apart from
cx0/snps). This makes it rather confusing when trying to
figure out which members belong to which platform(s).
Split the struct up into five different platform specific
sub-structures. For now this will actually increase the size
a little bit as we have to duplicate a few members from
skl to icl, but that will be remedied soon when we turn
the thing into a union.

Considering what the functions do, intel_dpll.c is a more suitable
location, and lets us make some functions static while at it.
This also means intel_display.c no longer does any DPIO access.

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.

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.
