Hi Valentine
This adds USBHS PHY and registers USBHS device if the driver is enabled.

Why it needs #if IS_ENABLED() ?
I guess nothing happen if renesas_usbhs driver
registered without CONFIG_USB_RENESAS_USBHS_UDC.
But am I misunderstanding ?
Since USB channel 0 is shared between PCI USB host and USBHS
we'll still need it later to properly configure the channel.
Besides, is saves us some bits leaving all the unused callbacks and
device structures out if we do not register the device when the driver
is disabled.
Thanks,
Val.
