We'll need to read back the watermark thresholds and occupancy from hardware (for devlink-sb integration), not only to write them as we did so far in ocelot_port_set_maxlen. So introduce 2 new functions in struct ocelot_ops, similar to wm_enc, and implement them for the 3 supported mscc_ocelot switches. Remove the INUSE and MAXUSE unpacking helpers for the QSYS_RES_STAT register, because that doesn't scale with the number of switches that mscc_ocelot supports now. They have different bit widths for the watermarks, and we need function pointers to abstract that difference away.
