The hardware path of vdosys1 with DPTx output need to go through by several modules, such as, PSEUDO_OVL and MERGE. Add DRM and these modules support by the patches below: Change in v2: - Merge PSEUDO_OVL and ETHDR into one DRM component. - Add mmsys config API for vdosys1 hardware setting. - Add mmsys reset control using linux reset framework.
