From: Emil Renner Berthing <[e-mail]>

This adds a driver for the temperature sensor on the JH7100, a RISC-V
SoC by StarFive Technology Co. Ltd., and most likely also the upcoming
JH7110 version.

The SoC is used on the BeagleV Starlight board:
https://github.com/beagleboard/beaglev-starlight

Support for this SoC is not yet upstreamed, but is actively worked on,
so it should only be a matter of time before that happens.

v2:
* Fix checkpatch.pl --strict warnings
  - Add myself to MAINTAINERS
  - Fix multiline comments
  - Use proper case and whitespace for #defines
  - Add comment to sfctemp::lock mutex.
* Remaining comments by Guenter Roeck
  - Add Documentation/hwmon/sfctemp.rst
  - Use devm_add_action() and devm_hwmon_device_register_with_info()
    instead of a driver .remove function.
  - Don't do test conversion at probe time.
  - #include <linux/io.h>
  - Remove unused #defines
  - Use int return variable in sfctemp_convert().
* Add Samin's Signed-off-by to patch 2/2
