Perhaps it suggests that OMAP4 (PandaBoard) serial port is already
activated but OMAP3 (BeagleBoard) isn't. So we need to reflect that
either by doing pm_runtime_set_active() only on OMAP4 or by bringing
up the OMAP3 too before the pm_runtime_set_active() call.
BTW I understand get_sync(), set_active() and enable() are for
different purposes, they can't be traded for one another.
