Due to conflicting/confusing defines in the vendor driver, we were
reading E2P_PHY_REG from the wrong location.
CR157 patching was slightly incorrect in that the vendor driver only
patches in an 8-bit value, whereas we were patching 24 bits.
Additionally, CR157 patching was happening on both zd1211 and zd1211b,
but this should only happen on zd1211.
