Underrun recovery was defeatured and was never brought into usage.
Thus we can remove the underrun recovery interrupt/reporting
register bits and related logic introduced to detect/report soft,
hard, port underruns.
Essentially this is a revert of the commit 8bcc0840cf
("drm/i915/xelpd: Enhanced pipe underrun reporting") which originally
added this functionality. Also note that PIPE_STATUS_UNDERRUN bit in
PIPESTATUS still stays relevant but we would move back to not
clearing this sticky bit as we are not using any information from
this register.

The function parse_lfp_panel_dtd() is called when the driver
attempts to initialize the eDP connector, and it allocates memory,
which is recorded in panel->vbt.lfp_vbt_mode. However, since no
eDP panel is connected, the driver fails at intel_edp_init_dpcd()
and follows the failure path. Unfortunately, the allocated memory
is not freed in this case.
To fix this issue, free the memory in the failure path.

Xe3's power well handling is similar to previous platforms, but there
are a few changes that need to be handled to ensure optimal power
management:
- PGB now only depends on PG1, not PG2
- Transcoder B is now in PG1 (was previously in PGB)
- Transcoders C & D are now in PG2 (were previously in PGC/PGD)
- DC states now require PG2 to be off (whereas on Xe2 it could remain
on as a dependency of PGB, although the features inside of it could
not be used).

A registered eDP connector is considered to be always connected, so it's
unnecessary to poll it for a connect/disconnect event. Polling it
involves AUX accesses toggling the panel power, which in turn can
generate a spurious short HPD pulse and possibly a new poll cycle via
the short HPD handler runtime resuming the device. Avoid this by
disabling the polling for eDP connectors.
This avoids IGT tests timing out while waiting for the device to runtime
suspend, the timeout caused by the above runtime resume->poll->suspend->
resume cycle keeping the device in the resumed state.

If the device is runtime suspended the eDP panel power is also off.
Ignore a short HPD on eDP if the device is suspended accordingly,
instead of checking the panel power state via the PPS registers for the
same purpose. The latter involves runtime resuming the device
unnecessarily, in a frequent scenario where the panel generates a
spurious short HPD after disabling the panel power and the device is
runtime suspended.

Currently we can call fence_fini() twice if something goes wrong when
sending the GuC CT for the tlb request, since we signal the fence and
return an error, leading to the caller also calling fini() on the error
path in the case of stack version of the flow, which leads to an extra
rpm put() which might later cause device to enter suspend when it
shouldn't. It looks like we can just drop the fini() call since the
fence signaller side will already call this for us.
There are known mysterious splats with device going to sleep even with
an rpm ref, and this could be one candidate.

Resources of swapped objects remains on the TTM_PL_SYSTEM manager's
LRU list, which is bad for the LRU walk efficiency.
Rename the device-wide "pinned" list to "unevictable" and move
also resources of swapped-out objects to that list.
An alternative would be to create an "UNEVICTABLE" priority to
be able to keep the pinned- and swapped objects on their
respective manager's LRU without affecting the LRU walk efficiency.
