ALSA: hda: Let LED cdev handling suspend/resume 

Set LED_CORE_SUSPENDRESUME to LED cdev flags, so that the LED core
would store and restore the LED status at suspend/resume.

In theory, the codec driver should be responsible for all LED bits,
but this might be safer and cover the overlooked cases.
