[PATCH] bcm43xx: Fix machine check on PPC for version 1 PHY

Recent changes in the specs that were introduced in commit
740ac4fb08866d702be90f167665d03759bd27d0 were incorrect and resulted in machine check
errors on the PPC architecture for G PHY's with a revision number equal to 1. The
two offending changes are reverted.
