* USB will be power OFF while it has been disconnecting

*
* mackerel can not use external interrupt (IRQ7-PORT167) mode on "USB0",

* It is impossible to use IRQ7 demux on this board.
*
* We can use external interrupt mode USB-Function on "USB1".
* USB1 can become Host by r8a66597, and become Function by renesas_usbhs.

* These uses same IRQ number for request_irq(), and aren't supporting
