drm/msm/dpu: skip watchdog timer programming through TOP on >= SM8450

Browse source 
The SM8450 and later chips have DPU_MDP_PERIPH_0_REMOVED feature bit
set, which means that those platforms have dropped some of the
registers, including the WD TIMER-related ones. Stop providing the
callback to program WD timer on those platforms.
