board/visionfive2, configs/visionfive2: add support for v1.2a board

Browse Source 
There are two revisions of the VisionFive 2: v1.2a and v1.3b. The main
difference between them is that v1.2a has one Gigabit Ethernet port and
one Fast Ethernet port, while v1.3b has two Gigabit Ethernet ports.

Unless explicitly set, U-Boot automatically sets $fdtfile based on the
EEPROM product data during initialization, enabling <fdtdir>/<fdtfile>
to be loaded via extlinux.conf.

Additionally, since $fdtfile contains the directory name, preserve the
directory structure of the DTBs when copying them to the target
directory.
