[PATCH v2 4/4] riscv: dts: starfive: don't use a default configuration

[Heinrich Schuchardt]

Booting JH7110 systems with a VisionFive 2 device-tree used to kind of
work without causing harm to the hardware. But there is no guarantee
that this will hold true in future. So we should not rely on it.

Before the current patch series booting failed on unsupported boards due
to the lack of a device-tree in the binman generated default configuration
when reaching main U-Boot.

By setting the default configuration to non-matching value booting will
now fail on unsupported boards already in SPL. This allows SPL to
continue with the next boot source for a possible recovery.
