This adds support for DSS subsystem present in TI's AM62L SoC
which supports single display pipeline with DPI output which
is also routed to DSI Tx controller within the SoC.
Change Log:
V3:
- Make generic infra to support truncated K3 DSS IP's
- Remove AM62A updates from AM62L DT binding updates

One generic question, do we have test case to verify whether the function is
working correctly? Thanks.
I think we could have IGT test case to trigger the fault, then have another IGT
test case to query it with this new uapi.
And make sure we could get the expected data with the new uapi.
