Read temperature of the speaker and expose it via hwmon interface, which
will be later used during calibration of speaker protection algorithms.

Merge series from Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>:
Few cleanups to make the code more robust or readable. No functional
impact (compiled objects stay the same).
Device has up to WSA884X_MAX_SWR_PORTS number of ports and the array
assigned to prop.sink_dpn_prop has 0..WSA884X_MAX_SWR_PORTS-1 elements.
On the other hand, GENMASK(high, low) creates an inclusive mask between
<high, low>, so we need the mask from 0 up to WSA884X_MAX_SWR_PORTS-1.
Theoretically, too wide mask could cause an out of bounds read in
sdw_get_slave_dpn_prop() in stream.c, however only in the case of buggy
driver, e.g. adding incorrect number of ports via
sdw_stream_add_slave().

Two arrays (with 'struct sdw_dpn_prop' and 'struct sdw_port_config')
store configuration of Soundwire ports, thus each of their element is
indexed according to the port number (enum wsa884x_port_ids, e.g.
WSA884X_PORT_DAC). Except the indexing, they also store port number
offset by one in member 'num'.
Entire code depends on that correlation between array index and port
number, thus make it explicit by using designators. The code is
functionally the same, but more obvious for reading.

Add support to parse static master port map information from device tree.
This is required for correct port mapping between soundwire device and
master ports.

On some boards with multiple WSA8840/WSA8845 speakers, the reset
(shutdown) GPIO is shared between two speakers. Use the reset
controller framework and its "reset-gpio" driver to handle this case.
This allows bring-up and proper handling of all WSA884x speakers on
X1E80100-CRD board.

This fix is based on commit [1] fixing click and pop sounds during
SoundWire port start because PA is left unmuted.
making use of new mute_unmute_on_trigger flag and removing unmute
at PA setup, removes the Click/Pop issue at SoundWire enable.
