Hello build bot (Jenkins),

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/52205

to look at the new patch set (#2).

Change subject: chromeec: introduce SSFC_OPTIONAL_IN_FW_CONFIG

chromeec: introduce SSFC_OPTIONAL_IN_FW_CONFIG

When EC_GOOGLE_CHROMEEC_INCLUDE_SSFC_IN_FW_CONFIG is enabled and SSFC is
not set, all fw_config is invalidated. But for some platform this may
not be necessary, we can treat missing SSFC as zero and use other 32
bits of firmware config.

Add Kconfig option 'EC_GOOGLE_CHROMEEC_SSFC_OPTIONAL_IN_FW_CONFIG' to
make this possible.
