soundwire: intel/cadence: update hardware reset sequence
Combining hardware reset with the multi-link mode leads to a shortened
hardware reset pattern observed on the bus.
The updated hardware programming sequence is to first enable the clock
with the sync_arm/sync_go pattern, and only in a second step to issue
the hardware reset sequence. Since there is no longer a dependency
between sync_arm/sync_go and hw_reset, the behavior of
sdw_cdns_exit_reset() is changed to wait for the self-clearing
CONFIG_UPDATE to go back to zero,
