guybrush: Add guybrush fw_configstabilize-glibc-13901.B-main
Each guybrush variant may have a different fw_config schema. Defining a
schema agnostic fw_config interface at baseboard. Each guybrush variant
must implement the interface. Fields that are not applicable outside a
specific variant do not need to be exposed in the baseboard interface.
