Introduce a Kconfig option EC_GOOGLE_CHROMEEC_FW_CONFIG_FROM_UFSC for
reading firmware configuration from Unified Firmware and Second-source
Config (UFSC) [1] from EC CBI. As the UFSC already includes both the
32-bit FW_CONFIG and 32-bit SSFC, this option is incompatible with
EC_GOOGLE_CHROMEEC_INCLUDE_SSFC_IN_FW_CONFIG.
Also check the size of the data read from CBI.
