Subject: [PATCH 2/3 v3] at91/USB: modify OHCI driver to allow shared interrupts

At91sam9g45 series has a set of high speed USB interfaces.
The host driver is an EHCI with its companion OHCI. OHCI is
always handled by ohci-at91.c.
This wrapper is just modified to allow IRQ sharing
between two controllers.
