Add support for the onboard hardware monitor for SG2042.
Can be tested with OpenSBI v1.5.

This patch is based on sophgo/for-next:
https://github.com/sophgo/linux/tree/sg2000/for-next

Changed from v10:
1. fix the hwmon entry permission.
2. remention the extra entry postion in the document.

Changed from v9:
1. remove missed wrong return value.
2. add document for the other interface of the driver.
3. rename repower_action to repower_policy.
4. use break to unify "return 0" in is_visible function.

Changed from v8:
1. rename critical_action to repower_action, and add some comment
2. remove unnecessary wrap function
3. use guard macro to simplify mutex process.

Changed from v7:
1. add mutex protected and fix the return value when writing
"critical_action"

Changed from v6:
1. restore the driver name to sg2042-mcu
2. remove unnecessary wrap function and check in the driver.
3. add dts and config entry.

Changed from v5:
1. rename driver name to sgmcu as it will support more sophgo chip.
2. move some attr to debugfs.
3. add standard crit_hyst support
4. add documentation

Changed from v4:
1. use fix patch for binding ref.
2. use unevaluatedProperties instead of additionalProperties for binding

Changed from v3:
1. add thermal-sensor check.
2. change node type from syscon to hwmon

Changed from v2:
1. fix bindings id path.

Changed from v1:
1. Move patch from soc to hwmon.
2. Fix typo.
