soc/intel/apollolake: Let coreboot set the VendorID and Subsystem ID
Set all FSP S UPDs that set IDs to 0, which allows them to be set
by coreboot.
Tested on StarLite Mk IV and LPC now has the correct device ID of
0x31e8, where previously it had 0x7270.
The UPDs differ APL and GLK, but the ones configured in this patch
have been there since their initial releases.
