usb: renesas_usbhs: add autonomy mode
Current renesas_usbhs was designed to save power when USB is not connected.
And it assumed platform uses callback to notify connection/disconnection
by external interrupt.
But some SuperH / platform board doesn't have such feature.
This patch adds autonomy mode which detect USB connection/disconnection
by internal interrupt.
But power will be always ON when autonomy mode is selected.
