Boards such as * PRIME X570-P, * ROG STRIX B550-F GAMING WIFI II, * ROG STRIX B550-XE GAMING (WI-FI), * ROG STRIX X570-E GAMING, * ROG STRIX Z390-F GAMING, * ROG STRIX Z390-H GAMING, * ROG STRIX Z390-I GAMING, * ROG STRIX Z490-A GAMING, * ROG STRIX Z490-E GAMING, * ROG STRIX Z490-F GAMING, * ROG STRIX Z490-G GAMING, * ROG STRIX Z490-G GAMING (WI-FI), * ROG STRIX Z490-H GAMING have got a nct6775 chip, but by default there's no use of it because of resource conflict with WMI method. This commit adds such boards to the WMI monitoring list.
