drm/msm/sde: interface TE interrupt implementation

sde 4.0.0 has tear-effect logic in ping-pong module whereas it
is moved to interface module in sde 5.0.0. The interrupt signals
in handling tear-effect logic are also moved to interface module.

This change implements the interrupt management hooks to handle
tear-effect logic present in interface module.
