Subject: [PATCH v1] msm:disp:dpu1: setup display datapath for SC7180 target

SC7180 follows a newer architecture where in some flush controls have been re-organized to simplify programming and provide for future expandability. 
Specifically:
1) The TIMING_<j> bits that control flush of INTF_<j> have been replaced with a common INTF flush bit which flushes the programming in the MDP_CTL_<id>_INTF_ACTIVE register
2) Individual flush bits for MERGE_3D, DSC and CDWN have been added which flush the programming in the MDP_CTL_<id>_MERGE_3D_ACTIVE, ... etc respectively
3) PERIPH flush bit has been added to flush DSP packets for DisplayPort

The complete datapath is described using the MDP_CTL_<id>_TOP and newly added ACTIVE registers to handle other sub blocks
such as interface (INTF) resources, PingPong buffer / Layer Mixer, Display Stream Compression (DSC) resources, writeback (WB) and 3D Merge 
selections that are part of the datapath.
