ASoC: codecs: wsa884x: report temps to hwmon in millidegree of Celsius

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
--
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:

wsa884x-virtual-0
Adapter: Virtual device
temp1:        +39.0°C
--
wsa884x-virtual-0
Adapter: Virtual device
temp1:        +37.0°C

Tested on sm8550 only.
