Treat USB vendor and product IDs like PCI subsystem vendor and device IDs
respectively to allow describing USB devices as `0000 0000 $vid $pid` in
the hardware database.
As a side effect, this also skips potentially expensive MTD lookups on
embedded devices with plugged in USB radios.
With a 5.15 kernel, such MTD lookups even spam dmesg with:
mtdblock: MTD device 'factory' is NAND, please consider using UBI block devices instead.
This fix speeds up iwinfo considerably on affected systems:

Don't add the hwmode A for radios which do not support 5GHz operation.
Before, this hwmode was added to all non-VHT radios regardless of their
supported bands.
Fixes commit 562d015326 ("iwinfo: nl80211: fix hwmode parsing for multi-band NICs")
Signed-off-by: David Bauer <mail@david-bauer.net>
In case a NIC supports multiple frequency bands, the supported
hw-modelist might not contain all valid hwmodes, as B/G/AD hwmodes are
only included based on the last parsed supported frequency.
In case a radio supports multiple bands, this might result in these
hwmodes not being flagged as supported.
Circumvent this by tracking all seen frequency bands using a bitmask
which later determined which HW modes are listed as supported.

As it's the most reliable and straight forward way on modern platforms,
detect the hardware ID by checking the 'compatible'-string of non-PCI
(ie. built-in) devices.
As this is only relevant for WiSoCs, there won't be that many records,
so it's not worth making any larger structural changes. Hence just
match the compatible string and translate it into fake PCI IDs.

The mac80211.sh implementation of the uci "path" option compares the
readlink() results of each /sys/class/ieee80211/*/device link to find
the proper phy directory while iwinfo so far tried to construct a full
path out of the uci value.
The iwinfo approach appears to fail under certain circumstances, e.g.
with Hyper-V systems utilizing PCI passthrough for the radio devices.
This commit mimicks the behaviour of mac80211.sh more closely to
achieve the same results.
