Subject: [PATCH 4/5] at91/USB: USB drivers modifications for at91sam9g10

From: Hong Xu <hong.xu@...el.com>

Modify both host and gadget USB drivers for at91sam9g10.
This add a clock management equivalent to at91sam9261 on usb drivers.
It also add the way of handling gadget pull-ups (like the at91sam9261).
