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 01/10] MIPS: BCM63XX: move fallback sprom support into its own
+ unit
+
+In preparation for enhancing it, move it into its own file. Require a
+mac address to be passed as the argument to always "reserve" the mac
+regardless of the inclusion state of SSB.
