wifi: mt76: mt7915: configure noise floor reporting on reset
When performing a full system recovery of the MCU on a dual-phy
platform, band 0 (usually 2.4GHz) stops reading correct noise floor
data.
This is due to noise floor reporting only being configured correctly
for the second device PHY.
Configure the respective registers correctly after restarting the MCU
firmware to fix reported noise-floor values.
