Refactor ATCSMU (System Management Unit) support by moving it from a system utility into a dedicated FDT-based HSM driver. Key changes include: - Moving the functions in lib/utils/sys/atcsmu.c into the new HSM driver - Moving hart start and stop operations on AE350 platform into the new HSM driver - Converting the assembly-based functions in sleep.S to C code for the readability - Updating the ATCWDT200 driver Signed-off-by: Ben Zong-You Xie <ben717@andestech.com> Signed-off-by: Leo Yu-Chi Liang <ycliang@andestech.com> Link: https://lore.kernel.org/r/20251229071914.1451587-2-ben717@andestech.com Signed-off-by: Anup Patel <anup@brainfault.org>
