Basavaraj Natikar bbf0dec306 HID: amd_sfh: Update HPD sensor structure elements
HPD sensor data is not populating properly because of wrong order of HPD
sensor structure elements. So update the order of structure elements to
match the HPD sensor data received from the firmware.

Fixes: 24a31ea949 ("HID: amd_sfh: Add initial support for HPD sensor")
