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.
BUG=b:211954778
TEST=Able to build google/brya with these changes.
> localhost ~ # lspci -xxx | less
00:00.0 Host bridge: Device 8086:4601 (rev 04)
Bit 0 for all PAM registers a.k.a, PAMx_0_0_0_PCI.LOCK bit is set
(meaning locked).
