Instead of iterating for hw ctrl per physical encoder, this
patch moves the iterations and assignment to the virtual encoder.

changes in v2:
	- none
changes in v3:
	- none

Instead of setting each one to null in the loop:

        struct dpu_hw_ctl *hw_ctl[MAX_CHANNELS_PER_ENC] = { NULL };

Remove once hw_ctl is initialized properly
