Move all of the SBIUnit-related code into the lib/sbi/tests directory. Update 'Makefile' to index objects from the tests subdirectory. I don't think creating the full separate list of Makefile variables (libsbitests-objs-path-y, libsbitests-object-mks, etc. as it is done for libsbiutils) is necessary for the tests because: 1) `lib/sbi/tests/objects.mk` is already indexed into 'libsbi-objects-mks' since the find expression for the libsbi-object-mks variable looks for objects.mk files in the nested directories as well). 2) Tests are tightly coupled with the `lib/sbi/` sources, therefore it may be reasonable to store the list of lib/sbi and lib/sbi/tests object files together in the libsbi-objs-path-y variable. Additionally, update relative paths in the tests where necessary. Signed-off-by: Ivan Orlov <ivan.orlov0322@gmail.com> Reviewed-by: Anup Patel <anup@brainfault.org>
