More preparatory patches for the DSA probe refactoring. The first three patches turn the Marvell drivers into individual modules, and a shared library module. They also become real Linux devices, with probe functions. However, at the moment, this is just stub code to be filled out with later patches.
With the drivers becoming real devices, it becomes easier to interact with device tree properties. One such driver property is a GPIO line used for resetting the switch. This is only used in Marvell devices, so move it out of the core code into the Marvell shared code. This changes the existing binding, but no in tree device tree actually uses it. The REG_READ and REG_WRITE macros have caused problems in the past, since they contain a return statement, messing up locking code. They also assume a ds variable is available. Kill them off. With the addition of the drivers becoming devices, the order in which data structures are created is changing. Previously, the DSA framework would create the dsa_switch structure and pass it to the setup() method, which would then allocate the driver private structure. Now the drivers probe as devices, they allocate there private structure first, and will only get a dsa_switch structure later. Future changes to have the device export its own MDIO bus rather than have the framework do it, requires at some of the driver functions operate using only the private structure. Perform a mass internal API change to pass the private structure internally, and only pass the dsa_switch structure for the public APIs. Each driver maintains a table of IDs to name strings. Extending this table with the number of ports a switch has. It is likely this will get further extended with number of VLANs, address databases etc. The mv88e6131 driver does something different for a single switch vs a collection of switches. All other drivers don't special case a single switch. There is no need to do this, so remove the special case. This will help later with unifying this code into the shared library. So nothing too interesting here, that will come later...
