[PATCH 5/9] powerpc/powernv: Fix endian for return value from pnv_tce_get()

[Gavin Shan]

This fixes the warning reported from sparse:

  gwshan at gwshan:~/sandbox/l$ make C=2 CF=-D__CHECK_ENDIAN__ \
                             arch/powerpc/platforms/powernv/pci.o
        :
  arch/powerpc/platforms/powernv/pci.c:761:16: \
  warning: incorrect type in return expression (different base types)
  arch/powerpc/platforms/powernv/pci.c:761:16: \
  expected unsigned long
  arch/powerpc/platforms/powernv/pci.c:761:16: \
  got restricted __be64 [usertype] <noident>
