USB: modifications for at91sam9g10
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). Signed-off-by: Hong Xu <hong.xu@atmel.com> Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>
