Broadcom wireless patch, PCIE/Mactel support

http://www.kernel.org/git/?p=linux/kernel/git/bcollins/ubuntu-dapper.git;a=commitdiff;h=1373a8487e911b5ee204f4422ddea00929c8a4cc

This patch adds support for PCIE cores to the bcm43xx driver. This is
needed for wireless to work on the Intel imacs. I've submitted it to
bcm43xx upstream.

(cherry picked from d88edf6a433074323a1805365a8dfc9c26fceae3 commit)
(cherry picked from 7dbd83ed3255fde4371edcbb6ad1d30f3e6ddf08 commit)
