drivers/i2c/w83795: Add full support for core functions
Add full support for fan control, fan monitoring, and voltage
monitoring. Fan speeds and functions are configurable via
each mainboard's devicetree.cb file.
NOTE: This patch effectively rewrites large portions of
the original driver. You may need to re-verify correct
operation on your hardware if you were using the old
driver code.
