ENGR00261419 MX6Q HDMI CEC: Unit test failed put TV to powerdown.

TV will been setting powerdown state when first run HDMI CEC unit
test on MX6Q, but failed in the secondly run and loop in print
message:
sleep for ready!
sleep for ready!
sleep for ready!
...

It is cause by cec interrupter been enabled before interrupter
polarity setting, controler will received fake interrupter,
and cec unit test will get wrong device state.

Fix the issue with move interrupter polarity setting code before
interrupter enabled.
