Human presence detection (HPD) sensor uses a camera to determine when
user is physically in front of the machine.  This might not be a
desirable behavior because it can (for example) cause the machine to
wake on approach.

Add a new sysfs file "hpd" that will control whether this sensor is
enabled. Use the value of this sysfs file to turn off HPD and prevent
it from re-enabling after resume from suspend.
