usb: dwc3: pci: Don't set "linux,phy_charger_detect" property on Lenovo Yoga Tab2 1380
The Lenovo Yoga Tablet 2 Pro 1380 model is the exception to the rule that devices which use the Crystal Cove PMIC without using ACPI for battery and AC power_supply class support use the USB-phy for charger detection. Unlike the Lenovo Yoga Tablet 2 830 / 1050 models this model has an extra LC824206XA Micro USB switch which does the charger detection. Add a DMI quirk to not set the "linux,phy_charger_detect" property on the 1380 model. This quirk matches on the BIOS version to differentiate the 1380 model from the 830 and 1050 models which otherwise have the same DMI strings.
