[PATCH v4 04/26] MIPS: sgi-ip27: drop HAVE_ARCH_NODEDATA_EXTENSION

Commit f8f9f21c7848 ("MIPS: Fix build error for loongson64 and
sgi-ip27") added HAVE_ARCH_NODEDATA_EXTENSION to sgi-ip27 to silence a
compilation error that happened because sgi-ip27 didn't define array of
pg_data_t as node_data like most other architectures did.

After addition of node_data array that matches other architectures and
after ensuring that offline nodes do not appear on node_possible_map, it
is safe to drop arch_alloc_nodedata() and HAVE_ARCH_NODEDATA_EXTENSION
from sgi-ip27.
