Enabling the active/passive shared boosts requires setting SYNC_EN, but
*not* before receiving the PLL Lock signal.
Solve the issue by setting the SYNC_EN bit in PWR_CTRL3 register right
after receiving the PLL Lock interrupt.
Additionally, drop the unnecessary writes to PWR_CTRL1 register, part of
the original mdsync_up_seq, which would have toggled GLOBAL_EN with
unwanted consequences on PLL locking behavior.

Looks good. If it's convenient to revise again, I think you could slim
down the comment section by simply stating that 'PLL Lock requires the
audio clocks to be active' (which is why it is not triggered until after
snd_pcm_start).
