Add support for t7xx WWAN device firmware flashing & coredump collection
using fastboot interface.

Using fastboot protocol command through /dev/wwan0fastboot0 WWAN port to
support firmware flashing and coredump collection, userspace get device
mode from /sys/bus/pci/devices/${bdf}/t7xx_mode.

## Form letter - net-next-closed

The merge window for v6.8 has begun and we have already posted our pull
request. Therefore net-next is closed for new drivers, features, code
refactoring and optimizations. We are currently accepting bug fixes only.

Please repost when net-next reopens after January 22nd.

RFC patches sent for review only are obviously welcome at any time.
