arm: mach-k3: Do not map ATF and OPTEE regions in MMU

Browse source 
ATF and OPTEE regions may be firewalled from non-secure entities. To
prevent access to this area we leave a hole there in the MMU map. This
is the same idea as [0] but we complete that patch by adding the same
for AM65, J721e, J7200, and J721s2 here.
