MIPS: sgi-ip27: drop HAVE_ARCH_NODEDATA_EXTENSION

Browse Source 
Commit f8f9f21c78 ("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.
