Add i915 parameter to I915_STATE_WARN() and use device based logging.
Done using cocci + hand edited where there was no i915 local variable
ready.

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

Replace the somewhat obscure crtc_state.update_pipe checks
with a more descriptive thing. Also nicely matches the
intel_crtc_needs_modeset() counterpart for full modesets.

Pull all the skl+ watermark code (and the dbuf/sagv/ipc code
since it's all sort of intertwined and I'm too lazy to think
of a finer grained split right now) into its own file from the
catch-all intel_pm.c.
Also sneak in the s/dev_priv/i915/ rename while at it.

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

Add new file intel_modeset_verify.c for high level modeset verification
code to declutter intel_display.h. The new file is supposed to be about
crtc/encoder/connector verification; the state verification for very
specific functionality such as plls or wm should be placed next to the
code it verifies.
Fix some minor checkpatch issues while at it.
