Shimoda, Yoshihiro 5ea4399457 usb: renesas_usbhs: add support for SUDMAC
The SUDMAC uses 8-bit width only. So, when the driver uses SUDMAC,
we have to clear the MBW_32.

Kuninori Morimoto f427eb64f4 usb: gadget: renesas_usbhs: support otg pin control
some renesas_usbhs device is supporting OTG external device interface.
In that device, it is necessary to control PWEN/EXTLP on DVSTCTR.
This patch support it.
But renesas_usbhs driver doesn't have OTG support for now.

Kuninori Morimoto e73a9891b3 usb: renesas_usbhs: add DMAEngine support
USB DMA was installed on "normal DMAC" when SH7724 or older SuperH,
but the "USB-DMAC" was prepared on recent SuperH.
These 2 DMAC have a little bit different behavior.

This patch add DMAEngine code for "normal DMAC",
but it is still using PIO fifo.
The DMA fifo will be formally supported in the future.

You can enable DMA fifo by local fixup
usbhs_fifo_pio_push_handler -> usbhs_fifo_dma_push_handler
usbhs_fifo_pio_pop_handler  -> usbhs_fifo_dma_pop_handler
on usbhsg_ep_enable.

This DMAEngine was tested by g_file_storage on SH7724 Ecovec board

Kuninori Morimoto bc57381e63 usb: renesas_usbhs: use delayed_work instead of work_struct
This delay is used to overjump debounce.

And, this patch also move usbhsc_drvcllbck_notify_hotplug to global,
because it will be called from other files.

Kuninori Morimoto f1407d5c66 usb: renesas_usbhs: Add Renesas USBHS common code
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.
