There are 5 L4 watchdogs and one SDM triggered warm reset bit in Agilex5 reset manager "stat" register where bit 16:20 for L4 watchdogs. Assigning value 1 to these bits in the register address will initiate SDM to trigger warm reset. Introducing new warm reset mask for Agilex5 to trigger warm reset to all five L4 watchdogs.
