* 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.
* But don't select both drivers in same time.
* These uses same IRQ number for request_irq(), and aren't supporting
* IRQF_SHARED / IORESOURCE_IRQ_SHAREABLE.
*
* Actually these are old/new version of USB driver.
* This mean its register will be broken if it supports shared IRQ,
