powerpc/83xx: fix build failures on dt compatible list.

Commit a4f740cf, "of/flattree: Add of_flat_dt_match() helper function"
introduced build failures in arch/powerpc/platform/83xx by mistyping
'static' as 'struct' in the compatible string list, and omitting a few
semicolons.  This patch fixes it.
