Implement the test which covers some of the functions from the `riscv_locks.h` file. This test consists of 3 test cases: 1) For lock/unlock functions 2) Unsuccessful trylock (the lock was previously taken) 3) Successful trylock (the lock is free and can be taken) Signed-off-by: Ivan Orlov <ivan.orlov0322@gmail.com> Reviewed-by: Anup Patel <anup@brainfault.org>
