Bring SDIO devices back to full power before their suspend handler is invoked. Doing so ensures that SDIO suspend/resume semantics are maintained (drivers still get to decide whether their card should be removed or kept during system suspend, and at what power state), and that SDIO suspend/resume execution paths are unchanged. This is achieved by resuming a runtime-suspended SDIO device in its ->prepare() PM callback (similary to the PCI subsystem). Since the PM core always increments the run-time usage counter before calling the ->prepare() callback and decrements it after calling the ->complete() callback, it is guaranteed that when the system will come out of suspend, our device's power state will reflect its runtime PM usage counter.
