soc: Add Kconfig for each soc vendor

Allows explicit ordering for vendors that share a common configuration
that must be sourced last.

The issue is that chips in soc/{amd,intel}/[ab].* will be able to
override defaults set in this file, but Kconfig files that get sourced
later (soc/amd/[d-z].*) will NOT be able to override these defaults.

Note: intel and amd soc chips now need to be added manually to the new
Kconfig file
