usb: dwc3-meson-g12a: fix usb2 PHY glue init when phy0 is disabled
When only PHY1 is used (for example on Odroid-HC4), the regmap init code
uses the usb2 ports when doesn't initialize the PHY1 regmap entry.
This fixes:
Unable to handle kernel NULL pointer dereference at virtual address 0000000000000020
