Lars-Peter Clausen 853342b201 altera: adi_jesd204: Disable FPLL phase alignment mode
Enabling the phase alignment mode of the FPLL seems to break manual
re-calibration, which is required when changing the lane rates. The
calibration seems to select the wrong VCO frequency band and the PLL no
longer locks.

Disable phase alignment mode for now, this has a negative effects on
deterministic latency, but it is better than not working at all.

Waiting for feedback from Altera/Intel on how to make manual re-calibration
work in phase alignment mode.
