Some combinations of hosts cannnot detect mt7921e after reboot. The
interoperability issue is caused by the status mismatch between host
and chip fw. In such cases, the driver should stop chip activities
and reset chip to default state before reboot.

As comment of pci_get_device() says, it returns a pci_device with its
refcount increased. We need to call pci_dev_put() to decrease the
refcount. Save the return value of pci_get_device() and call
pci_dev_put() to decrease the refcount.

The commit 006b9d4ad5 introduced phy->band_idx to accommodate the
band definition change for mt7986 so that the band_idx of main_phy
can be 0 or 1. Accordingly, the source of band_idx 1 has switched to
"phy != &dev->phy" or "dev->phy.band_idx = 1".
We still use ext_phy to represent band 1 somewhere in driver, so fix it.
Also, band_idx sounds more reasonable than dbdc_idx, so change it.

The firmware can have the capability to manage the channel context
scheduling on multiple roles running on the device including Station,
AP and P2P GC/GO mode (will be extended based on the future patchset)
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.

mt7915 does not have a per-band number of chains unlike the other chips,
it only has a total number of chains. Yet the current code would
consider the total number as a per-band number.
For example, it would report that a 2x2 + 2x2 DBDC card have 4 chains on
each band and set chainmask to 0b1111 for the first interface and
0b11110000 for the second.
