Christopher Braga 78439dfaf7 disp: msm: dp: Update sink sync check to be disabled by default ...

The DP standard leaves ambiguity to if sink synchronization
will be set before auxiliary protocols such as HDCP are to begin.
Update the dp_display HDCP worker  to check sink sync only if
explicitly instructed to via the new debugfs node 'hdcp_wait_sink_sync'
