[00/19] mt76: improve runtime-pm support

Rework runtime-pm support introduce pm refcounting in order
to fix some leftover races between fw_own and tx/rx path.
Introduce awake/doze time accounting.
This is a preliminary series to enable 'deep sleep' support in
mt7921 firmware.

Lorenzo Bianconi (19):
  mt76: mt7921: fix a race between mt7921_mcu_drv_pmctrl and
    mt7921_mcu_fw_pmctrl
  mt76: mt7663: fix a race between mt7615_mcu_drv_pmctrl and
    mt7615_mcu_fw_pmctrl
  mt76: connac: introduce wake counter for fw_pmctrl synchronization
  mt76: mt7921: rely on mt76_connac_pm_ref/mt76_connac_pm_unref in tx
    path
  mt76: mt7663: rely on mt76_connac_pm_ref/mt76_connac_pm_unref in tx
    path
  mt76: dma: add the capability to define a custom rx napi poll routine
  mt76: mt7921: rely on mt76_connac_pm_ref/mt76_connac_pm_unref in tx/rx
    napi
  mt76: mt7663: rely on mt76_connac_pm_ref/mt76_connac_pm_unref in tx/rx
    napi
  mt76: connac: unschedule ps_work in mt76_connac_pm_wake
  mt76: connac: check wake refcount in mcu_fw_pmctrl
  mt76: connac: remove MT76_STATE_PM in mac_tx_free
  mt76: mt7921: get rid of useless MT76_STATE_PM in mt7921_mac_work
  mt76: connac: alaways wake the device before scanning
  mt76: mt7615: rely on pm refcounting in mt7615_led_set_config
  mt76: connac: do not run mt76_txq_schedule_all directly
  mt76: connac: use waitqueue for runtime-pm
  mt76: remove MT76_STATE_PM in tx path
  mt76: mt7921: add awake and doze time accounting
  mt76: mt7921: enable sw interrupts
