Subject: [PATCH v4 06/26] MIPS: loongson64: drop HAVE_ARCH_NODEDATA_EXTENSION

From: "Mike Rapoport (Microsoft)" <rppt@...nel.org>

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

After rename of __node_data to node_data arch_alloc_nodedata() and
HAVE_ARCH_NODEDATA_EXTENSION can be dropped from loongson64.

Since it was the only user of HAVE_ARCH_NODEDATA_EXTENSION config option
also remove this option from arch/mips/Kconfig.
