Randy Dunlap d67ed2510d xtensa: use CONFIG_USE_OF instead of CONFIG_OF ... CONFIG_OF can be set by a randconfig or by a user -- without setting the early flattree option (OF_EARLY_FLATTREE). This causes build errors. However, if randconfig or a user sets USE_OF in the Xtensa config, the right kconfig symbols are set to fix the build.
