board: starfive: handle compatible property in dynamic DT configuration

The difference between the StarFive VisionFive 2 1.2A and 1.3B boards is
handled dynamically by looking at the PCB version in the EEPROM in order
to have a single u-boot version for both versions of the board. While
the "model" property is correctly handled, the "compatible" one is
always the the one of version 1.3b.

This patch add support for dynamically configuring that property.

Fixes: 9b7060bd15e7 ("riscv: dts: jh7110: Combine the board device tree files of 1.2A and 1.3B")
