bssinfo/starec disabled commands are sent during removing interface.
However, if we don't set corresponding enabled commands before
removing interface, the fw may enter an exception state due to
some NULL structs.
For example, the following commands can cause fw timeout in our newer
chips:
    ifconfig wlan0/mon0 up
    ifconfig wlan0/mon0 down

Fix this by setting enabled commands once interface added.

It is unnecessary to keep the interrupt enabled in mt76s_sdio_irq because
the driver is already aware of the interrupt, schedules the
mt76s_txrx_worker to handle the corresponding actions, and eventually,
the interrupt would be enabled again when mt76s_txrx_worker finishes its
work.

So we can safely disable the interrupt in mt76s_sdio_irq as soon as
possible to increase the CPU productivity by dropping the redundant
interrupt triggers.

Note that sdio lock acquired/released would be handled in sdio_irq_work
at mmc driver so we don't take care in mt76s_sdio_irq at function driver.

It doesn't guarantee the mt7921e gets started with ASPM L0 after each
machine reboot on every platform.

If mt7921e gets started with not ASPM L0, it would be possible that the
driver encounters time to time failure in mt7921_pci_probe, like a
weird chip identifier is read

[  215.514503] mt7921e 0000:05:00.0: ASIC revision: feed0000
[  216.604741] mt7921e: probe of 0000:05:00.0 failed with error -110

or failing to init hardware because the driver is not allowed to access the
register until the device is in ASPM L0 state. So, we call
__mt7921e_mcu_drv_pmctrl in early mt7921_pci_probe to force the device
to bring back to the L0 state for we can safely access registers in any
case.

In the patch, we move all functions from dma.c to pci.c and register mt76
bus operation earilier, that is the __mt7921e_mcu_drv_pmctrl depends on.

According to the firmware behavior (even the oldest one in linux-firmware)
If the firmware is downloaded, MT7921S must rely on the additional mailbox
mechanism that resides in firmware to check if the device is the right
state for mt7921s_mcu_[fw|drv]_pmctrl. Otherwise, we still apply the old
way for that.

That is a necessary patch before we enable runtime pm for mt7921s as
default.
