[Buildroot] [PATCH v1 1/1] boot/xilinx-prebuilt: simplify family logic

[Neal Frager]

Currently, the xilinx-prebuilt package uses an if-then-else statement for
deciding which files need to be installed from the xilinx-prebuilt repo. This
works fine for now because there are really only two options, either versal or
zynqmp/kria.

Starting with the xilinx_v2025.2 release, the versal2 family along with the
vek385 board will be added to Buildroot and thus the xilinx-prebuilt package
as well. In the future, additional families will also probably be added to
this package.

To avoid creating a long if-then-else-then-else statement which will only grow
in complexity over time, simplify the logic of the xilinx-prebuilt package by
giving each xilinx family its own if statement. In the long term, this will
make the xilinx-prebuilt package easier to understand and maintain.

For this reason, this patch moves the zynqmp/kria families from the "else"
statement to having their own if statement.
