[RFC/PATCH 1/2] usb_otg: compile fix

From: Francisco Alecrim <francisco.alecrim@openbossa.org>

include/linux/usb.h: In function 'usb_mark_last_busy':
include/linux/usb.h:561: error: 'struct usb_device' has no member named
'last_busy'

Option USB_OTG selects USB_SUSPEND but doesn't select PM(required by
USB_SUSPEND) causing this compile error. Putting USB_SUSPEND as
USB_OTG depend ensure that PM is selected.

For me it seems sufficient to just remove the select of USB_SUSPEND.
USB_OTG compiles fine without it.

Seems harsh to require someone to enable CONFIG_PM and USB_SUSPEND just
to compile OTG drivers.
