If use_mclk is false, mclk_mode is written to a register without
initialization. This doesn't cause any ill effects as the written value

To fix this, write use_mclk only when use_mclk is true.

Really? Ok, well, then it was a good random find =).
I did already push this to drm-misc-next, as I thought it does not have
any real effect. I'll check if it's ok to push to drm-misc-fixes too,
with Cc stable.
