Wrong DTB for StarFive VisionFive 2 v1.2a board

[AGreen BHM]

With the official image of 23.04 for the StarFive VisionFive 2 RISCV board there is no Ethernet (and possibly other issues) when installing on the hardware revision v1.2a. This is due to the DTB for this revision not being in the /boot directory and the Grub configuration only referencing the newer v1.3b revision. As a result, the board boots seemingly normally, but there is no Ethernet access available. If you modify the Grub configuration to point to the file "/lib/firmware/6.2.0-19-generic/device-tree/starfive/jh7110-starfive-visionfive-2-v1.2a.dtb" the issue is resolved after a reboot.
