drm/i915/mtl: Add Support for C10 PHY message bus and pll programming

XELPDP has C10 and C20 phys from Synopsys to drive displays. Each phy
has a dedicated PIPE 5.2 Message bus for configuration. This message
bus is used to configure the phy internal registers.

XELPDP has C10 phys to drive output to the EDP and the native output
from the display engine. Add structures, programming hardware state
readout logic. Port clock calculations are similar to DG2. Use the DG2
formulae to calculate the port clock but use the relevant pll signals.
Note: PHY lane 0 is always used for PLL programming.

Add sequences for C10 phy enable/disable phy lane reset,
powerdown change sequence and phy lane programming.

Bspec: 64539, 64568, 64599, 65100, 65101, 65450, 65451, 67610, 67636

drm/i915: Make M/N checks non-fuzzy

Now that we no longer fuzz M/N during fastset these should
match exctly.

In order to get a match with what the BIOS does we need to round
M/N down. And we do the opposite rounding when doing the readback.
That gets us pretty much the same thing back.

There can still be slight rounding differences between FDI M/N
vs. the DPLL output so we allow for tiny deviation in
intel_pipe_config_sanity_check().

v2: Tweak rounding/sanity check stuff a bit
