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:

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.

v3:
* Handle timeouts from wait_for_completion_interruptible_timeout
properly.

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
