RTEMS | Copyright/license/SPDX Issues with files generated by rtems-bin2c (#5335)

[Joel Sherrill (@joel)]

## Summary

We use rtems-bin2c to turn files into arrays of unsigned characters. These arrays can be compiled and embedded into programs. This is used for a tar file containing the initial file system image, device tree, and more. The generated files in the RTEMS source tree are a hodge podge of no license/attribution and odd attributions that need to be reviewed. At least the following files are impacted:

- testsuites/fstests/fsdosfsname01/image.h
- testsuites/fstests/fsdosfsname01/files.h
- testsuites/fstests/fsdosfsname01/image_bin_le_multibyte.h
- testsuites/fstests/fsdosfsname01/image_bin_le_singlebyte.h
- testsuites/fstests/fsdosfsname01/init.c
- testsuites/libtests/libfdt01/some.h
- testsuites/libtests/libfdt01/some.c
- testsuites/libtests/ofw01/some.c
- testsuites/libtests/ofw01/some.h
- bsps/arm/imxrt/dts/imxrt1050-evkb.c
- bsps/arm/imxrt/dts/imxrt1166-cm7-saltshaker.c
- bsps/riscv/riscv/include/bsp/beaglevfire.h
- bsps/riscv/riscv/include/bsp/kendryte-k210-dtb.h
- bsps/riscv/riscv/include/bsp/mpfs-dtb.h
- bsps/aarch64/raspberrypi/fdt/rpi4b_dtb.c
- bsps/microblaze/microblaze_fpga/include/bsp/microblaze-dtb.h

We need to decide what to do with these files. It seems wrong to claim attribution for the bin2c version of a device tree. 

I think rtems-bin2c may need some additions to help with this. 

- option (-2) to just insert 2-BSD SPDX and license.
- automatically generated comment to follow Doxygen style for @file and include the name of the source file
- option (?) for SPDX string. Already has option for license file to insert.
