arm: socfpga: agilex5: Add warm reset mask for Agilex5
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.
