Subject: [PATCH v3 0/3] Add support for AM62L DSS

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

V2:
- Fix incorrect format of compatible string (comma instead of
  hyphen) for AM62L SoC
- Use separate register space and helper functions for AM62L
  due to minor differences in register offset/bit position differences
  for first plane
