[PATCH] bcm43xx-softmac: update PHY initialization 

This patch updates the PHY initialization code for bcm43xx-softmac
to conform with recent changes in the clean-room specs at
http://bcm-specs.sipsolutions.net. Mostly, these changes implement
the sequence needed for chips with GPHY revision 8; however, the
patch also corrects a typo in one address, and some parts that were
missing from the spec when the initial coding was done.
