ASoC: codecs: rt1308-sdw: remove duplicate allocation
The .read_prop callback is supposed to be called by the SoundWire core
only. Calling it again from this driver results in an additional
memory allocation for no good reason.

ASoC: codecs: rt*-sdw: fix memory leak in set_sdw_stream()
Now that the sdw_stream is allocated in machine driver,
set_sdw_stream() is also called with a NULL argument during the
dailink shutdown.

In this case, the drivers should not allocate any memory, and just
return.

Detected with KASAN/kmemleak.

ASoC: codecs: rt*-sdw: don't assign slave_ops
The SoundWire bus core already assigns the slave ops, no need to set
them a second time manually in each driver.

These messages are generated at each enumeration, this is

ASoC: rt1308-sdw: use slot and rx_mask to configure stream
If the DAI was configured with a set_tdm_slots() call, use the information.

A platform or machine driver may configure each amplifier to extract
different bitSlots from the frame, or extract the same data and use
processing to generate the relevant output. The latter case is easier
to handle in case of orientation changes.
