[PATCH] powerpc/pseries: Fix IBM_ARCH_VEC_NRCORES_OFFSET for POWER8 updates

[Michael Neuling <mikey@neuling.org>]

In supporting POWER8 we added 16 bytes to the start of the
ibm_architecture_vec, but forgot to add this to
IBM_ARCH_VEC_NRCORES_OFFSET.

This caused us to hit this warning in early boot:
  WARNING ! ibm_architecture_vec structure inconsistent: 805372128

This add this extra 16 bytes of offset.
