2dac6381c3da net: wwan: t7xx: Add fastboot WWAN port
d27553c14f06 net: wwan: t7xx: Infrastructure for early port configuration
409c38d4f156 net: wwan: t7xx: Add sysfs attribute for device state machine
e3caf184107a wwan: core: Add WWAN fastboot port type

[Test Case]
1. Boot to OS.
2. Insert sim card to the system.
3. Check the gnome-settings with WWAN settings or check with command mmcli -L
4. Repeat 1, 2, 3 multiple times and make sure WWAN always exists and works well

[Where problems could occur]
Hard to tell, but ODM and us did some tests and confirmed the WWAN does keep working during 1900 reboot stress test.

=============
At booting up:

mtk_t7xx 0000:56:00.0: enabling device (0000 -> 0002)
mtk_t7xx 0000:56:00.0: Invalid device status 0x1
