disp: msm: sde: add support for WD timer on INTF

Watchdog timer is moving from TOP to INTF. This change adds
support for movement and ensures backwards compatibility.

Vsync select only needs to specify whether or not to use
Timer 0 associated with the interface. It does not need to
select between Timer 0-4.
