[0/9] usb/dwc3 / phy/tusb1210: Add TUSB1211 charger detection

Message

Some Android x86 tablets with a Bay Trail (BYT) SoC (with DWC3 UDC)
and a Crystal Cove PMIC, which does not support charger-detection,
rely on a TUSB1211 phy for charger-detection.

This series adds support for this, it starts with some dwc3 bug-fixes
for issues hit while developing this, as well as adding support to
the dwc3 code to set a special property checked by the tusb1210 driver
to signal that it needs to enable charger-detection.

The 2nd half of the series does some refactoring / fixes to the
tusb1210 driver and adds the charger-detection support.

Regards,

Hans
