soc/intel/xeon_sp: move PCH specific code into lbg directory

pmc_lock_smi() and pmc_lockdown_config() have PCH specific
implementations. Move them from common lockdown.c and pmc.c
into lbg/soc_pmutil.c.

Move sata_lockdown_config() and spi_lockdown_config() to
lbg/lockdown.c.

While here, fix some coding style issues.
