* Update to SDFat upstream 2.2.2
Pull in reformatted/slightly refactored SDFat 2.2.2 upstream.
Very minor changes, simple testing on other architectures passed w/o
incident.
* Fix SdFat to build for ESP8266
2.2.2 removed a define from the configuration header which is needed to
compile on the ESP8266. Restore the default values there previously.
* SDFat Debug tests not compatible, skip
