docs/system/arm: Split fby35 out from aspeed.rst

The fby35 machine is not implemented in hw/arm/aspeed.c,
but its documentation is currently stuck at the end of aspeed.rst,
formatted in a way that it gets its own heading in the top-level
list of boards in target-arm.html.

We don't have any other boards that we document like this; split it
out into its own rst file. This improves consistency with other
board docs and means we can have the entry in the target-arm
list be in the correct alphabetical order.
