Add support for vbus detection and power supply. This code is more or
less stolen from phy-gpio-vbus-usb.c, and aims at providing a detection
mechanism for VBus (ie. usb cable plug) based on a GPIO line, and a
power supply activation which draws current from the VBus.

when checking if our generic PHY is enabled,
it's a lot easier to use IS_ENABLED() instead
of manually checking for it. While at that, also
remove the bogus defined(MODULE) at the end of
the line.

it's now very easy to return a platform_device pointer
and have the caller pass it as argument when calling
usb_phy_generic_unregister().
