Merge patch series "arm: dts: k3-am62a: remove GP security variant for AM62A"

Bryan Brattlof <bb@ti.com> says:

The AM62Ax was created right when TI was shifting to their high security
(HS-FS and HS-SE) processes. During this transition a small subset of
AM62A parts where configured to use the old "GP" security for internal
and for select groups of partners but never sold for the wider public.

To help simplify the build and to avoid any confusion of which security
configurations are supported going forward remove the GP builds for the
AM62A SoCs.
