soc/intel/skylake: permit Kconfig to set subsystem ID

Browse Source 
This change permits the subsystem ID to be specified via Kconfig for the
devices on the SoC.

Some devices are getting zero'ed subsystem IDs because the unset (and thus
zero'ed) config options are overwriting the fsp defaults. With this change
the fsp defaults will only be overwritten by non-zero config values.
