wifi: mt76: mt7921: get rid of the false positive reset

Browse Source 
False positive reset would be possibly triggered by those commands we
applied in suspend with HZ MCU timeout, especially it happened when we
enabled kernel log in pm core to diagnose how much time we spend in each
driver during suspend procedure. So we enlarge the value and align the MCU
timeout as other commands we did to reduce the false positive reset.
