PMUFW: MOD: Add DAP Wake Module

Add DAP event handler to PMU Firmware as a new user module and pass on
the handling to respective ROM Handlers.When a DAP wake arrives,
PMU should ACK the DAP Wake using its local registers.
PMU ROM has handlers for these and we will re-use these handlers here.
This module is enabled only if ENABLE_PM is not defined to avoid conflict
with the PM module
