intel_{mpllb,c10pll}_state_verify() blows up if you call them
for a non-modeset/fastset commit on account of the relevant
connector not being part of the overall atomic state.
Currently the state checker only runs for modeset/fastset
commits, but for testing purposes it is sometimes desirable
to run it for other commits too. Check for modeset/fastset
in intel_{mpllb,c10pll}_state_verify() itself to make this safe.
v2: Give the new intel_c10pll_state_verify() the same treatment
Add comment to explain why we do this

Turns out many of the files that need i915_reg.h get it implicitly via
{display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h
-> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h,
makes sense to drop it, but that requires adding quite a few new
includes all over the place.
Prefer including i915_reg.h where needed instead of adding another
implicit include, because eventually we'll want to split up i915_reg.h
and only include the specific registers at each place.
Also some places actually needed i915_irq.h too.

This will help to support 4k@30 mode for HDMI monitors on DG2.

If one of our PHYs fails to complete calibration, we should skip the
general initialization of the corresponding output. Most likely this is
going to happen on outputs that don't actually exist on the board; in
theory we should have already decided to skip this output based on the
VBT, but we can't always rely on the VBT being accurate.

Our early understanding of DG2 was incorrect; since the 5th display
isn't actually a Type-C output, 38.4 MHz input clocks are never used on
this platform and we can drop the corresponding MPLLB tables.

The PORT_TC1 port is not yet enabled properly in the driver, but
intel_phy_snps.c is relying on intel_phy_is_snps() to filter out
unavailable phys. That function was already considering the last phy as
available. Just correct the offset of the last phy to 0x64C14 as the

In order to have per-lane drive settings we need intel_ddi_level()
to accept the lane as a parameter. That is, the eventual goal is to
call intel_ddi_level() once for each lane. For now we just pass in
a hardcoded 0 and use the same settings for every lane. Ie. no
change in behaviour yet.
