obsw/bsp_z7/ps7_cortexa9_0

This is based on the bsp of the zynq_fsbl in https://github.com/Xilinx/embeddedsw/tree/xilinx_v2024.1/lib/sw_apps/zynq_fsbl

It is generated/collected by xilinx's build system when building the fsbl.

Currently, version xilinx_v2024.1 is used.

We use our own CMakeLists.txt located in the subfolders of libsrc to select which files to include in our bsp.

Xilinx exports CMakeLists.txt files for some of their folders as well, which we remove to avoid confusion.

Additionally, drivers from https://github.com/Xilinx/embeddedsw/tree/xilinx_v2024.1/XilinxProcessorIPLib/drivers are added as needed.
