2dac6381c3 net: wwan: t7xx: Add fastboot WWAN port 
On early detection of wwan device in fastboot mode, driver sets
up CLDMA0 HW tx/rx queues for raw data transfer and then create
fastboot port to userspace.

Application can use this port to flash firmware and collect
core dump by fastboot protocol commands.
E.g., flash firmware through fastboot port:
 - "download:%08x": write data to memory with the download size.
 - "flash:%s": write the previously downloaded image to the named partition.
 - "reboot": reboot the device.

409c38d4f1 net: wwan: t7xx: Add sysfs attribute for device state machine 
Add support for userspace to get/set the device mode, device's state
machine changes between (unknown/ready/reset/fastboot).

Get the device state mode:
 - 'cat /sys/bus/pci/devices/${bdf}/t7xx_mode'

Set the device state mode:
 - reset(cold reset): 'echo reset > /sys/bus/pci/devices/${bdf}/t7xx_mode'
 - fastboot: 'echo fastboot_switching > /sys/bus/pci/devices/${bdf}/t7xx_mode'
Reload driver to get the new device state after setting operation.
