SCMI-enabled boards may restrict access to resources like clocks, resets
and regulators to the secure world.
A normal world bootloader or kernel compatible with the non-SCMI-enabled
board is thus not guaranteed to be able to deal with the SCMI variant.
It follows, that the SCMI-enabled board is not compatible with the
non-SCMI enabled board, so drop that compatible.
This change is motivated by the barebox' bootloader's use of bootloader
specification files[1][2]: barebox for non-SCMI DK2 will compare its
own top-level "stm32mp157c-dk2" compatible with all compatibles
listed in the device tree referenced by each bootloader spec file.
If the boot medium contains a configuration with
compatible = "st,stm32mp157c-dk2-scmi", "st,stm32mp157c-dk2", "st,stm32mp157";
it will match, because of the second compatible and boot a kernel with
SCMI enabled, although no SCMI may exist on the platform.
