Remove runtime_pm support from rsc driver. RSC driver
does not vote for MMCX. It relies on sde core driver
to keep vote and trigger call. That brings additional
dependency to manage runtime_pm references during
pm_suspend/pm_resume call. This change also updates
the runtime_pm call to manage the pm_suspend in
msm drm driver.

The encoder idle work is scheduled during the frame-done event
to be executed after a timeout. During the execution, the check
for any on-going/pending frames is invalid as it checks for > 1.
Fix it to check for any non-zero frame-pending and avoid
power-collapse.

During secure-ui, the SMMU, MISR and VBIF states
are altered based on the enable/disable of secure-ui
which is followed by the scm_call. Failure in any of
the steps would lead the system to an unstable state.
Address all the failures and revert back all steps
to get the system back in original state to avoid
any issues.

With posted-start, ctl scheduler status and pending-kickoff
count are checked to address the missing pp-done interrupt
cases, which can occur if the IRQs are disabled for a long
time by some entity. Currently this check is done after
the wr-ptr-irq. At this point the scheduler status may
or may not be idle, based on the frame-transfer. Move this
handling after the timeout, so the scheduler is guaranteed
to be in idle state for working use-case.

Some Type-C multi-port adapters which do not support usb connection
are advertising the multi-functionality in DP alt mode. If
multi-functionality is preferred, the DP driver assumes the adapter
supports usb connection and USB phy driver will program the PHY mode
to DP+USB.
In source mode, usb PD driver checks for the peer_usb_connection
of the adapter. If it does not support usb then it will stop usb stack
and update the PHY MODE to USB only mode from phy_suspend path.
The result is, usb may program the combo PHY to usb only mode when DP
is already connected. This is causing AUX read/write timeouts when DP
is trying to access the phy registers.
To fix this issue, a flag in SVID connect handler in usbpd driver to
notify peer_usb_comm support to the DP driver. DP driver will read this
flag and program the phy mode.

Switch to watchdog vsync whenever panel jitter is
identified during frame-transfer on command mode display.
This would allow the HW to finish processing the frame
with watchdog vsync source. Switch back to default vsync
source after the frame-transfer is complete. This would
help in the MDP hang issues in panels that generate TEs
with thresholds greater than the projected jitter.
