[PATCH 4/6] ARM: dts: stm32mp: ev1: build extra device tree with SCMI

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

Devices with SCMI are booted by the ARM Trusted Firmware-A out of a FIP
bundle. The FIP bundle contains barebox-stm32mp-generic-bl33.img along
with a device tree. Let's build SCMI enabled device trees as well for
the EV1, which we already support in non-SCMI mode.
