Allow user to focus/select disabled preferences.

On the sound preferences screen, when in auto/never mode, the
user should be able to scroll down and see all the supported
surround sounds formats, even if the switches are disabled.

Bug: 76167503
Test: Verified user can now scroll down on sound preferences screen.
