Revert "adv7481: return error when PLL lock fails"

Browse source 
This reverts commit 44d8abb6e0.

If we return error on PLL lock failure, it results in open_stream
failure for TIF. So, if we open the TV app first and then connect
HDMI cable, it will not start streaming. Therefore reverting this
change.
