Settings: rotation settings for devices with hardware rotation lock
All settings would be disabled on devices with hardware rotation
lock due to dependency setting. Disable dependency to allow setting
swap volume and rotation degrees on those devices.

Add lockscreen rotation as an optional rotation setting (2/2)
This will allow the user to select wether or not to use the
rotation settings for the lockscreen.  This is dependent
upon the rotation setting being checked.
