[Buildroot] [PATCH v2 1/1] boot/xilinx-prebuilt: add local versal xsa support

[Neal Frager via buildroot]

Most of the time, users will be running Vivado on their local host machine,
and will generate a XSA (Xilinx Shell Archive) locally.

Instead of requiring users to create a URL location for their XSA file,
this patch improves ease of use by allowing users to work directly with
just a path on the local host machine.

BR2_TARGET_XILINX_PREBUILT_VERSAL_XSA_LOCATION can thus be defined as either
a simple local location or a URL location for the XSA file.

In either case, a hash for the XSA file needs to be added to the
boot/xilinx-prebuilt/xilinx-prebuilt.hash when using this option.
