renesas_usbhs has default callback functions and settings.
And it tried overwrite to platform private data
if platform doesn't have them.
So, if renesas_usbhs was compiled as module,
it will be hung-up on 2nd insmod.
This patch fixup it.

This is mod_host prototype support for renesas_usbhs driver.
It doesn't support USB-Hub, and USB-DMAC for now.

current mod_gadget had got usb speed on
usbhsg_irq_dev_state() which is status change interrupt callback function.
And the usb speed data was included in its parameter.
But this style works for mod_gadget,
but doesn't work for mod_host which
isn't interrupted when device status was changed.
This patch add usbhs_bus_get_speed() to solve this issue.

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.

Renesas SuperH has USBHS IP which can switch Host / Function.
This driver is designed so that Host / Function may dynamically change.
This patch add usb/renesas_usbhs and common code for SuperH USBHS.
