[PATCH] bcm43xx: Fix for 4311 and 02/07/07 specification changes

The specifications for the bcm43xx driver have been modified. This
patch incorporates these changes in the code, which results in the
BCM4311 and BCM4312 working. The name of one of the PHY parameters,
previously known as "version", has been changed to "analog", short for
"analog core version" .
