net: mscc: ocelot: convert QSYS_SWITCH_PORT_MODE and SYS_PORT_MODE to regfields
Currently Felix and Ocelot share the same bit layout in these per-port registers, but Seville does not. So we need reg_fields for that. Actually since these are per-port registers, we need to also specify the number of ports, and register size per port, and use the regmap API for multiple ports. There's a more subtle point to be made about the other 2 register fields: - QSYS_SWITCH_PORT_MODE_SCH_NEXT_CFG - QSYS_SWITCH_PORT_MODE_INGRESS_DROP_MODE which we are not writing any longer, for 2 reasons: - Using the previous API (ocelot_write_rix), we were only writing 1 for Felix and Ocelot, which was their hardware-default value, and which there wasn't any intention in changing. - In the case of SCH_NEXT_CFG, in fact Seville does not have this register field at all, and therefore, if we want to have common code we would be required to not write to it.
