ssb: Handle alternate SSPROM location
In kernel Bugzilla #15825 (2 users), in a wireless mailing list thread (http://lists.infradead.org/pipermail/b43-dev/2010-May/000124.html), and on a netbook owned by John Linville (http://marc.info/?l=linux-wireless&m=127230751408818&w=4), there are reports of ssb failing to detect an SPROM at the normal location. After studying the MMIO trace dump for the Broadcom wl driver, it was determined that the affected boxes had a relocated SPROM. This patch fixes all systems that have reported this problem.
