Instead of hard-coding ATF and OPTEE addresses in firewall configuration
templates, use K3_*_LOAD_ADDR. Doing so ensures that if someone moves
ATF/OPTEE regions, the change gets picked up by binman without
explicitly having to modify dts files.

Not an issue with this patch, this is better than before, but we still have
the size of TF-A and OP-TEE hardcoded here, and also here[0]. Might be good
to add a Kconfig symbol for the size of these at some point.
