wifi: mt76: mt7925: add handler to hif suspend/resume event

Browse Source 
When the system suspend or resume, the WiFi driver sends
an hif_ctrl command to the firmware and waits for an event.
Due to changes in the event format reported by the chip, the
current mt7925's driver does not account for these changes,
resulting in command timeout. Add flow to handle hif_ctrl
event to avoid command timeout. We also exented API
mt76_connac_mcu_set_hif_suspend for connac3 this time.
