HID: amd_sfh: Default to HPD disabled
Unless you know to look for it, HPD is a surprising behavior; particularly
because it can wake the system from suspend. It also has implications for
power consumption because sensors are left enabled.
After the sensors have been probed (and HPD is found present), explicitly
turn off HPD by default. Userspace can manually turn it on if desirable.
