[RFC PATCH 15/19] arm: dts: k3-j7200: Remove background firewall on DDR

With updated TIFS version tag v11.02.06, the background firewall
for DDR firewalls are applied by the TIFS. This removes the
dependency of applying firewalls through binman.

Remove background firewall on the whole DDR, as this
background firewall is applied by the TIFS init for j7200
and j784s4. Modify for j7200 only, as there are no firewalls applied
for j784s4 from SPL.
