[Qemu-ppc] [PATCH] Revert "hw/ppc/spapr_pci.c: Avoid functions not in glib 2.12 (g_hash_table_iter_*)"

[Markus Armbruster]

Since we now require GLib 2.22+ (commit f40685c), we don't have to
work around lack of g_hash_table_iter_init() & friends anymore.

This reverts commit f8833a37c0c6b22ddd57b45e48cfb0f97dbd5af4.
