Kuninori Morimoto 66ee3bef3c ARM: mach-shmobile: mackerel: add renesas_usbhs support for USB1
renesas_usbhs driver can use external interrupt mode
(which come from USB-PHY) or autonomy mode (it use own interrupt)
for detecting connection/disconnection when Function.
And it will be power OFF while it has been disconnecting
if external interrupt mode is selected.

mackerel board has 2 USB ports.

But we can not use external interrupt mode
on CN22 USB0 port which is only for USB Function.
IRQ7-PORT40 is already used by Touchscreen,
and USB-PHY needs IRQ7-PORT167.
It is impossible to use IRQ7 demux on mackerel.

We can use external interrupt mode USB-Function on "USB1".
USB1 can become Host by r8a66597, and become Function by renesas_usbhs.
But don't select both drivers in same time.
These 2 drivers are not supporting IRQ SHARD.
