USB OHCI support for at91sam9g45 SoC
Add USB OHCI support for at91sam9g45ekes/at91sam9m10g45ek boards. Note that according to errata from Atmel, OHCI is not operational on the first revision of at91sam9g45 chip. So this patch enables OHCI support for later revisions. Signed-off-by: Sergey Matyukevich <geomatsi@gmail.com>
