soundwire: stream: Move remaining register accesses over to no_pm

There is no need to play with the runtime reference everytime a register
is accessed. All the remaining "pm" style register accesses trace back
to 4 functions:

sdw_prepare_stream
sdw_deprepare_stream
sdw_enable_stream
sdw_disable_stream

Any sensible implementation will need to hold a runtime reference
across all those functions, it makes no sense to be allowing the
device/bus to suspend whilst streams are being prepared/enabled. And
certainly in the case of the all existing users, they all call these
functions from hw_params/prepare/trigger/hw_free callbacks in ALSA,
which will have already runtime resumed all the audio devices
associated during the open callback.
