[PATCH 1/2] dt-bindings: firmware: amlogic,meson-gxbb-sm: add amlogic,meson-s4-sm

[christian . koever-draxl]

From: Christian Stefan Kövér-Draxl <ckoever@xxxxxxxxxx>

The S4 secure monitor implements the GXBB interface, but its PSCI
SYSTEM_OFF needs an extra firmware call first (a shutdown flag), so the
driver has to tell it apart. Add an S4 compatible with the GXBB one as
fallback.
