arm: mach-k3: arm64-mmu: do not map ATF and OPTEE regions in A53 MMU

ATF and OPTEE regions may be firewalled from non-secure entities.
If we still map them for non-secure A53, speculative access may happen,
which will not cause any faults and related error response will be ignored,
but it's better to not to map those regions for non-secure A53 as there
will be no actual access at all.

Create separate table as ATF region is at different locations for am64
and am62/am62a.
