board: starfive: DeepComputing FML13V01 fdt selection

We support all JH7110 boards with starfive_visionfive2_defconfig.
The relevant device-tree is selected at runtime based on EEPROM data.

Support setting $fdtfile to the file name of the DeepComputing Framework
motherboard (FML13V01) device-tree.
