Currently, we don't powerdown the stack if it is not up but if the recovery work completes after freeze, then the device will be up afterwards. This will not be a sane situation. So let's flush the recovery worker before trying to powerdown the device.

After that, the devices will be powered down so that the system can enter the target sleep state. During this stage, the PCI core will put the devices in D3hot. But this transition is allowed by the MHI spec. The devices can only enter D3hot when it is in M3 state. So for fixing this issue, let's add the poweroff() callback that will get executed before putting the system in target sleep state during hibernation. This callback will power down the device properly so that it could be restored during restore() or thaw() stage.

However, the quirk handling added for gpt12 caused a regression for system suspend for am335x as the PM coprocessor needs the timers idled for suspend. Let's make the gpt12 quirk specific to omap34xx, other SoCs don't need it. Beagleboard revisions C and later no longer need to use the gpt12 related quirk. Then at some point, if we decide to drop support for the old beagleboard revisions A to B4, we can also drop the gpt12 related quirks completely.
