wifi: mt76: mt7921: reduce polling time in pmctrl

Browse Source 
Due to the polling tick is 10ms, the wake up flow in the status waiting
would cause more 10~20ms than the real HW response time. Reduce
tick-interval from 10ms to 1ms to get better network performance, such
as ping latency, in low power mode.
