[ Upstream commit 1f432e4cf1dd3ecfec5ed80051b4611632a0fd51 ]
Boards G15CF has got a nct6775 chip, but by default there's no use of it
because of resource conflict with WMI method.
Add the board to the WMI monitoring list.

[ Upstream commit 305790dd91057a3f7497c9d128614a4f8486b62b ]
It seems the mlxbf-pmc driver is missing initializing sysfs attributes
which causes the warning below when CONFIG_LOCKDEP and
CONFIG_DEBUG_LOCK_ALLOC are enabled. This commit fixes it.
