brcm63xx: rework fallback sprom support

Rework fallback sprom support by providing different sproms for
different chips. Also make it optional to use.

This likely causes sprom fallback support to break on a few boards.

+Subject: [PATCH 03/10] MIPS: BCM63XX: make fallback sprom optional
+
+Some devices do not provide enough mac addresses to populate wifi in
+addition to ethernet.
+
+Use having pci enabled as a rough heuristic which boards should have it
+enabled.
