lib: utils/hsm: factor out ATCSMU code into an HSM driver
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
