2021-03-17sar: Fix semantics of `get_wifi_sar_cbfs_filename()`Furquan Shaikh
Currently, if `get_wifi_sar_cbfs_filename()` returns NULL, then `get_wifi_sar_limits()` assumes that the default filename is used for CBFS SAR file. This prevents a board from supporting different models using the same firmware -- some which require SAR support and some which don't. This change updates the logic in `get_wifi_sar_limits()` to return early if filename is not provided by the mainboard. In order to maintain the same logic as before, current mainboards are updated to return WIFI_SAR_CBFS_DEFAULT_FILENAME instead of NULL in default case.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.
