[PATCH 3/3] ARM: dts: Add muxing for wl12xx on the SDIO bus for blaze

This should work assuming the board-4430sdp.c works, but it seems
that I don't have the "1283 PG 2.21 connectivity device" on
my blaze. Anybody got a spare connectivity device for blaze?

Also, if somebody has the schematics, please provide a patch
for the missing GPIO muxes for blaze, see the the panda for
what's currently missing.
