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.

Yes, this has also moved to INTF starting sm8450.
Note : wd timer programming in interface is missing, so that support
needs to be added as well
For this change,
