[PATCH] Documentation: riscv: bring BeagleV Starlight docs up-to-date

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The BeagleV Starlight hasn't exited the Beta phase and the BeagleV name
is now associated with the BeagleV-Ahead, which used a different SoC.

Note this in the section title and also adjust the build instruction to
make them reproducible in 2024:

  - Given that the board is discontinued, it's not worthwhile to move
    away from the vendor's OpenSBI fork, so pin the revision that was
    used for initial bring-up

  - fence.i is no longer part of the default -march=rv64imafdc in
    recent toolchains, therefore add it explicitly into the ISA string.
