net: dsa: mv88e6xxx: remove wait and update routines
Now that we have proper Wait Bit and Wait Mask routines, remove the unused mv88e6xxx_wait routine and its Global 1 and Global 2 variants. The indirect tables such as the Device Mapping Table or Priority Override Table make use of an Update bit to distinguish reading (0) from writing (1) operations. After a write operation occurs, the bit self clears right away so there's no need to wait on it. Thus keep things simple and remove the mv88e6xxx_update helper as well.
