soundwire: stream: Add specific prep/deprep commands to port_prep callback
Currently, port_prep callback only has commands for PRE_PREP, PREP, and POST_PREP, which doesn't directly say whether this is for a prepare or deprepare call. Extend the command list enum to say whether the call is for prepare or deprepare aswell. Also remove SDW_OPS_PORT_PREP from sdw_port_prep_ops as this is unused, and update this enum to be simpler and more consistent with enum sdw_clk_stop_type. Note: Currently, the only users of SDW_OPS_PORT_POST_PREP are codec drivers sound/soc/codecs/wsa881x.c and sound/soc/codecs/wsa883x.c, both of which seem to assume that POST_PREP only occurs after a prepare, even though it would also have occurred after a deprepare. Since it doesn't make sense to mark the port prepared after a deprepare, changing the enum to separate PORT_DEPREP from PORT_PREP should make the check for PORT_PREP in those drivers be more logical.
