During virt enable call, sde_enc master will be removed and
re-assigned. If an underrun is observed during this
scenario, it results in crash due to uninitialized access.
This change handles the above scenario.

The splash memory initialized by the bootloader needs

The change adds a new mode property allowed_mode_switch. The new
property is a 32bit bitmask that indicates the modes each mode
can switch to. This change is required to pass the driver mode
switching capabilities, so that user mode can reject any mode switch
that is not supported by the driver.

This change fixes the vblank wait after system cache read mode

Allow for overriding color processing features that normally uses
DSPP flush to use LM flush instead. This is required on targets

Trusted VM adapts splash handoff path to acquire the same
set of HW blocks the tui display was using in the primary VM
before switching out.
To use the splash handoff path, Trusted VM should add an
additional vote to the PM so that refcounts will be remain
balanced after the splash path cleanup at the completion
of the first valid commit.
This change adds the needed vote and as a result cleans up
explicit voting from trusted vm commit paths.

When resuming the video session from a source initiated power down, the
dp_display driver is doing a link probe again to override the previous
link information parameters. The link_probe is not accurately capturing
all the sink capabilities resulting in the link getting trained at a
different rate when resuming from a PM suspend or a secure display
session. The HBR3 support is indicated in the extended capabilities
DPCD registers which is not considered in the upstream link probe
implementation.
This change will remove the drm_dp_link_probe function from the DP
driver because it is not capturing the accurate DP sink capabilities.
