ssb: Convert to use of the new SPROM structure
In disagreement with the SPROM specs, revision 3 devices appear to have
moved the MAC address.

Change ssb to handle the revision 4 SPROM, which is a different size.
This change in size is handled by adding a new variable to the ssb_sprom
struct and using it whenever possible. For those routines that do not
have access to this structure, a 'u16 size' argument is added.

The new PCI_ID for the BCM4328 is also added.

Testing of the Revision 4 SPROM, which is used on the BCM4328, was done
by Michael Gerdau <mgerdau@tiscali.de>.
