OMAP:HACK - don't let CORE go to off-mode the first time.
If CORE and USBHOST both go the off-mode the first time
USBHOST does, then my device will not resume.
However if we let USBHOST go to off-mode and back will CORE is
in RETENSION at most, then subsequent off-mode transitions are
not a problem.
So for RETENTION for the first transition, and OFF for the next.
