Acquire mngr clk_mutex before updating link clock frequencies.
Failing this may lead to race around condition while setting the
link clock frequency rates.
Make sure byteclk and pclk rates of PLL are configured according
to clock manager and not the controller.

In the case of DSI underflow or overflow, skip enabling back the DSI error
interrupts and instead send panel_dead. The error interrupt will be enabled
later by HAL as part of handling panel_dead event. Not enabling back the
DSI error interrupts immediately can prevent IRQ storm from occurring.

In current SDE driver, DSC resource allocation is done in
reverse order for DP displays. If this DSC resource allocation
invoked with array previously chosen DSC blocks, dereferencing
the array should be in same order of resource allocation to
avoid index mismatch and resource allocation failure.

Adds a check for payload's vc_start_slot before attempting to finish
payload allocation. vc_start_slot is set to -1 on payload allocation
part 1 failure.
Prevents calling mst helper function on failed payload allocation.

When HDCP enabled sink reports a link failure, it should
be a warning instead of an error because it can be part
of expected behavior during encryption level changes as
per spec. Also now prints debug statement on min enc
level changes.

Sporadic link training failures occur when panel doesn't
respond to updating of link parameters.
Re-initialize panel after a link training failure when
the link rate is downshifted. Fixes sporadic lt failures.

During display disable, ensure source pipes are detached
from control path in the disable commit itself. Otherwise,
if other display acquire these pipes immediately it can hang
as these pipes are still staged on current display ctl path.

This change decrements the specific drm connector's reference count
after it has been used for reading crc frame value. Without this
change, there might be a chance of a connector's reference count
still remaining positive, even if it is not accessed anywhere
