swsusp: avoid emergency disk parking in "platform" mode

Hi,

although the issue seems fixed on normal shutdown and with swsusp in "shutdown" mode, i still get the ugly "clunk" of my emergency-parking disk in platform mode.
The attached patch fixes this for me, although i am not sure this is the correct way to do. Probably some device_suspend(SOMETHING) would be better and maybe the device_power_down is no longer needed, but something needs to be done at this point.
