Merge patch series "Firewall ATF and OP-TEE memory regions in Sitara"

Suhaas Joshi <s-joshi@ti.com> says:

This series starts by replacing hard-coded addresses in firewall
templates that are defined in k3-binman.dtsi, by Kconfigs. Using
Kconfigs makes it easier for someone to move ATF and OP-TEE to another
location, since they wouldn't have to fiddle with the firewall
configurations in dtsi files.

The rest of the commits in this series add firewall configs to each
device's dtsi files.

I have only tested this patch series with TI boards. For non-TI Sitara
boards, respective board maintainers are requested to test the relevant
patch and confirm whether it works.

To test this, I used `k3conf <read|write> <address> [<value>]`. Both of
these operations were disallowed, as expected.
