usb: misc: onboard_usb_dev: Add support for requesting VBUS for Type-A ports

Browse source

Add a regulator-only entry matching OF-described USB Type-A connectors.

This allows platforms to explicitly model VBUS supply regulators for these
ports instead of calling them PHY supplies or making the respective
regulators always-on in their device trees.

Type-A ports won't typically need a dedicated driver, as there is nothing
to configure apart from the power supply, so there is no controller driver
to traverse the OF graph and request the VBUS regulator, unlike for Type-C
ports. Thus make it an onboard USB device, which it kind of really is.
