USB-C CC pins are pulled to the GND by AW3512 (VCONN switches) when VCONN is off

Try using one of the recent pre-built Mobian images. I just compared fresh installs of a recent nightly build (20200715) I had against an older one (20200707). The older one didn't have anything in /sys/class/typec, but the more recent one did. I was able to use the more recent pre-built image to update the firmware. It looks like the current images should now include the anx7688 driver, so there should be fewer hoops to jump through to get USB peripherals working.

I also double checked whether pinephone-devtools was needed for it, and it looks like it isn't, so scratch that.
