USB: r8a66597-hcd: host controller driver for R8A66597

I would like to submit Renesas R8A66597 USB HCD driver.

R8A66597 is Renesas USB 2.0 host and peripheral combined
controller device originally designed for embedded products.
As a limitation of this device, it does not support externel
hub more than 2 tier, and cannot communicate with a USB
device more than 10. Then this device is not compatible with
EHCI and/or OHCI, I wrote driver support patch based on
sl811 code.

This driver has the following unique specifications:
- Implement transfer timeout to share one pipe with plural endpoint.
- Detach detection of a USB device connected to externel hub.

The driver has been tested external hub, usb-hdd, usb-cdrom,
usb-speaker, mice, keyboard, and usbtest driver.

Enable this option if your board has this chip, and you want
to use it as a host controller. If unsure, say N.
