Randy Dunlap 3d288ed983 xtensa: use CONFIG_USE_OF instead of CONFIG_OF 
[ Upstream commit d67ed2510d28a1eb33171010d35cf52178cfcbdd ]

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.

Fixes these build errors:
