USB: isp1362-hcd: Removes CONFIG_USB_OTG dependent code, fix build breakage

In today linux-next I got a compile error on usb/host/isp1362-hcd:

drivers/usb/host/isp1362-hcd.c: In function ‘isp1362_hub_control’:
drivers/usb/host/isp1362-hcd.c:1680: error: ‘ohci’ undeclared (first use in this function)

The problem is when the CONFIG_USB_OTG option is enabled.

ohci variable is never declared and there isn't any CONFIG_USB_OTG dependent code
besides the portion defined in isp1362_hub_control.

So I think that maybe USB OTG support is not needed/supported.

This patch removes the CONFIG_USB_OTG dependent block so the driver can compile cleanly.
