USB: host: ohci-at91: merge ohci_at91_of_init in ohci_hcd_at91_drv_probe
As device tree support is now mandatory, merge ohci_at91_of_init() in ohci_hcd_at91_drv_probe(). Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
