ARM: cns3xxx: use OHCI platform driver
This patch converts the cns3xxx platform to use the ohci-platform driver which is now suitable for use. A previous patch converted the cns3xxx platform to use the ehci-platform driver, and thus introduced the need to have power_{on,off} callbacks. Since both the EHCI and OHCI platform drivers use the same same power_{on,off} callbacks now, rename them to cns3xx_usb_power_{on,off} to show that they are shared.
