soc/intel/cmn/lockdown: Perform SA lockdown configuration
`sa_lockdown_cfg` function ensures locking the PAM register hence,
skip dedicated calling into `sa_lock_pam()` from the SoC
`finalize.c` file. Dropped sa_lock_pam() call from ADL/CNL/EHL/JSL
and TGL.
Additionally, this patch enforces SA lockdown configuration for SKL
and ICL as well.
