[POWERPC] 83xx: mpc832x mds: Fix board PHY reset code

currently the board-level PHY reset code for the mpc832x MDS messes with
reset configuration words source settings which is plain wrong (it
looks like this board code was cut-n-pasted from the mpc8360 mds code,
which has the PHY reset bits in a different BCSR); this patch points
the PHY reset code to the proper mpc832x mds PHY reset bits in the BCSR.
