Shayne ChenandFelix Fietkau 47799aefe2 wifi: mt76: change txpower init to per-phy
Use per-phy structure for maximum txpower value initializing, since each
phy may have a different chainmask, which can impact the calculation of
power gain.

The MIB INFO command is fetching MIB_BUSY_TIME, MIB_TX_TIME, MIB_RX_TIME and

busy should be >= tx + rx >= tx + bss_rx but we don’t always quite see this.
Sometimes tx + rx is a bit higher than busy due to inaccurate accounting,
so this patch recalculates numbers to make them more reasonable.
