Log:
  powerpc/booke: Fix Book-E boot post-minidump
  
  r353489 added minidump support for powerpc64, but it added a dependency on
  the dump_avail array.  Leaving it uninitialized caused breakage in late
  boot.  Initialize dump_avail, even though the 64-bit booke pmap doesn't yet
  support minidumps, but will in the future.
