Temperatures are reported in units of Celsius however hwmon expects
values to be in millidegree of Celsius. Userspace tools observe values
close to zero and report it as "Not available" or incorrect values like
0C or 1C. Add a simple conversion to fix that.
Before the change:
wsa884x-virtual-0
Adapter: Virtual device
temp1: +0.0°C

Also reported as N/A before first amplifier power on.
After this change and initial wsa884x power on:

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.
