google/chromeec: Add Kconfig option to enable / disable EC build
Add a Kconfig option to explicitly enable and disable the google
Chrome EC firmware build. Disabling the build will also disable
the software sync in the chipsets where it's enabled. On the
platforms where EC_SOFTWARE_SYNC is enabled in the mainboard Kconfig,
the select will need to be removed explicitly.

EC software sync is a mechanism where the AP helps the EC verify its
firmware similar to how vboot verifies the main system firmware. This
