This patch series enables HDCP in Cadence MHDP DPI/DP bridge driver.

Changes since v1:
- Move sapb reg block right after apb reg block
- Corresponding changes in binding and example

Changes since v2:
- Revert reg resource sequence in binding and 
  use resource mapping by name
- Remove hdcp_config from binding and use
  DRM HDCP Content Type property to select
  HDCP version

Changes since v3:
- Fix kernel test robot warning

Changes since v4:
- Fix binding issue

Changes since v5:
- Maintain backward compatibility of driver on platforms
  without SAPB port by allowing driver to continue without
  HDCP feature instead of returning error
