[PATCH] usb: phy: make GPIOs optional for the generic phy

[Paul Zimmerman]

The use of GPIOs should be optional for the generic phy, otherwise
the Altera SOCFPGA platform at least is broken.

Fixes breakage caused by a combination of e9f2cefb0cd "usb: phy: 
generic: migrate to gpio_desc" and 135b3c4304d "usb: dwc2: platform: 
add generic PHY framework support".
