Add a new flag may_power_off for scsi device, it gives the user a chance
to control when the device is runtime suspended, can we remove its power
if possible.

And if the device can be powered off(reflected by can_power_off flag,
determined by individual driver), create a sysfs entry named
may_power_off to let user control the flag.

Do we really need yet another interface to user space?
