[PATCH 7/8] usb: misc: onboard_usb_dev: add support for the Prolific PL2775

The Prolific PL2775 USB 3.0 to SATA bridge on the APQ8074 Dragonboard
has its RESET_N pin wired to a PMIC GPIO, so it stays in reset until
the OS releases it and the device never enumerates.

Add the PL2775 (067b:2775) to the onboard USB device driver as a
non-hub device with a single vdd supply and a conservative 1 ms reset
pulse.
