Subject[PATCH v9 03/10] firmware: Rename FW_OPT_NOFALLBACK to FW_OPT_NOFALLBACK_SYSFS
Date
This is a preparation patch for adding a new platform fallback mechanism,
which will have its own enable/disable FW_OPT_xxx option.

Note this also fixes a typo in one of the re-wordwrapped comments:
enfoce -> enforce.
