MIPS: loongson64: drop HAVE_ARCH_NODEDATA_EXTENSION

Commit f8f9f21c ("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.
