[PATCH] bcm43xx: Remove dead configuration variable CONFIG_947XX

The CONFIG_BCM947XX configuration variable was designed for use by the
embedded device used by the OpenWRT project. The device has been shifted
to the ssb driver in bcm43xx-mac80211 and will not be used with SoftMAC.
Accordingly, this "dead" configuration variable is removed.
