Subject: [PATCH 14/14] ARM: dts: stm32: introduce basic boot include on stm32mp15x board

From: Gabriel Fernandez <gabriel.fernandez@...s.st.com>

Include this .dtsi file to be backward compatible with old basic bootchain.

For example add:
#include "stm32mp15-no-scmi.dtsi" in a stm32mp157c*.dts file.
