sb/intel: Introduce SCMI Kconfig options

Introduce two options for enabling SMBus Control Method Interface [1] support.

1. HAVE_SCMI is to be set by southbridges that implements SCMI in the DSDT.
   That implementation should be conditional on USE_SCMI below.
2. USE_SCMI is guarded by HAVE_SCMI and actually provides the option to the
   user in Kconfig. Enabling it adds the SCMI implementation to the DSDT and
   make it usable. Boards that require this support for board function should
   set it in their BOARD_SPECIFIC_OPTIONS, which will lock this option on.

It will be used by CB:41735 but is designed for wider adoption e.g. by CB:44507
