Aaron Rossetto 3ef5cae77d N320: Revert PLL lock time reduction
This commit reverts the changes made in commit 81a9cc1f8 to reduce the
time for the LMK PLL to report lock status. The decision to revert the
change comes after an investigation found that reducing the overall time
to detect lock correlates with an increase in an error reported by the
TDC ('[ERROR] TDC measurements show a wide range of values!  Check your
clock rates for incompatibilities. ...  Uncaught exception in method
set_clock_source: TDC measurement out of expected range!').  Despite the
LMK PLL reporting lock status, our investigation revealed that it takes
additional time for the PLL to align the daughterboards' clocks closely
enough to pass the TDC measurement's range limit (i.e., no samples
exceeding the measurement mean +/- 500 ps). Reverting the change
increases the amount of time between achieving lock status and taking
the TDC measurements, thus greatly reducing the likelihood of the
reported error.
