wifi: mt76: mt7921: fix a potential association failure upon resuming

In multi-channel scenarios, the granted channel must be aborted before
suspending. Otherwise, the firmware will be put into a wrong state,
resulting in an association failure after resuming.
With this patch, the granted channel will be aborted before suspending
if necessary.

wifi: mt76: mt7921: fix CLC command timeout when suspend/resume

When enter suspend/resume while in a connected state, the upper layer
will trigger disconnection before entering suspend, and at the same time,
it will trigger regd_notifier() and update CLC, causing the CLC event to
not be received due to suspend, resulting in a command timeout.

Therefore, the update of CLC is postponed until resume, to ensure data
consistency and avoid the occurrence of command timeout.

We actually don't need the reserve the 512 entries for the MCU firmware
download Rx queue because the queue was only used in the firmware download
phase to save the most of space and the reduction can significantly help
with reducing latency we spent by ~20% further in resetting the Rx queue
as the device was waking up from deep sleep mode.

wifi: mt76: mt7921: get regulatory information from the clc event

The clc event can report the radio configuration for the corresponding

certain platform device.

This patch would change the clc commnad from no-waiting to waiting for
event. For backward compatible, we also add a new nic capability tag
to indicate the firmware did support this new clc event from now on.

to help users sharing the network with others on a single device.

The firmware is able to support the channel chanctx up to 2 interface
simultaneously running on the different channels.

Another thing to be noted is that before the driver is going sent out the
management frames, the driver has to get the privilege from the firmware
to occupy the current channel context until the frame handshake is
completed and then get the privilege back to the firmware.

mt76: mt7921e: fix possible probe failure after reboot

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.
