Power handle's interconnect interface assumes all interconnects
contain a reg bus entry, but RSC does not require one. Change
the logic to only report interconnect failure if the reg bus
node exists in the device node.

When switching from CMD to VIDEO or vice-versa, HW no longer
requires a vsync wait in between since the vsyncs will be
synchronized. So skip the wait for HW which supports this

Previous SB DMA logic was not clearing a "SB DMA active" flag, resulting
in SB DMA incorrectly being flushed every frame. While this logic
matches the DB DMA approach, it is unnecessary and could result in
delayed DB DMA execution.
Update SB DMA logic to clear the "active" flag for the target DSPP
immediately after the SB DMA is flushed.

For command mode panels, if a dynamic mode switch occurs on
the first frame, the current code skips DSI controller initialization
and registering for error handlers. This causes the software state
to be uninitialized for DSI CTRL, resulting in command transfer
failures and eventual crash. The change ensures that initialization
is complete even if the DMS occurs on first frame.

Create a new driver to handle sysfs and topology events that are
related to application/userspace layer interactions for HDCP
functionality. In turn, this will create a clear separation from
the HDCP QSEECOM layer that defines the communication mechanism

This implementation is based on a snapshot of the msm_hdcp
