[PATCH] zd1211rw: Fix E2P_PHY_REG patching
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.
