net: dsa: mv88e6xxx: add global1 helpers The Global (1) internal SMI device is an extended set of registers containing ATU, PPU, VTU, STU, etc. It is present on every switches, usually at SMI address 0x1B. But old models such as 88E6060 access it at address 0xF, thus using REG_GLOBAL is erroneous. Add a global1_addr info member used by mv88e6xxx_g1_{read,write} and mv88e6xxx_g1_wait helpers in a new global1.c file. This patch finally removes _mv88e6xxx_reg_{read,write}, in favor on the appropriate helpers. No functional changes here.

net: dsa: mv88e6xxx: add a soft reset operation Marvell chips have different way to issue a software reset. Old chips (such as 88E6060) have a reset bit in an ATU control register. Newer chips moved this bit in a Global control register. Chips with controllable PPU should reset the PPU when resetting the switch. Add a new reset operation to implement these differences and introduce a mv88e6xxx_software_reset() helper to wrap it conveniently.

net: dsa: mv88e6xxx: add PPU operations Some Marvell chips can enable/disable the PPU on demand. This is needed to access the PHY registers when there is no indirection mechanism.

net: dsa: mv88e6xxx: rework ATU GetNext Add and use a fresh documented implementation of the ATU GetNext. Since it is not necessary to write the MAC address to iterate from, only do it once directly in the ATU GetNext operation, if the provided ATU entry structure is not valid. This makes the user code simpler. Also, there is no need to loop when getting a single ATU entry. So remove the mv88e6xxx_atu_get helper and add a simpler snippet in mv88e6xxx_port_db_load_purge to lookup a given MAC address. The _mv88e6xxx_atu_mac_{read,write} are not used anymore thus remove them. _mv88e6xxx_atu_data_{read,write} are still used so keep them.

The static mv88e6xxx_g1_atu_{fid_write,op_wait,op,data_write,mac_write} functions won't need to be exposed in the end so for the moment keep their counterparts _mv88e6xxx_atu_{wait,cmd,data_write,mac_write} as is, since they are still used by other ATU operations.
