net: mdio: realtek-rtl9300: Groundwork for multi SOC support

The Realtek Otto switch platform consist of four different series

- RTL838x aka maple   : 28 port 1G Switches
- RTL839x aka cypress : 52 port 1G Switches
- RTL930x aka longan  : 28 port 1G/2.5G/10G Switches
- RTL931x aka mango   : 56 port 1G/2.5G/10G Switches

The existing realtek-rtl9300 MDIO driver was only designed for RTL930x
devices. The three other SOCs are not supported although they basically
incorporate a very similar MDIO controller.

This series is the first step in a multi-stage approach to also support
the missing SOCs. Device specific properties and registers are converted
into designated initializers. Based on this new devices can be added
much easier in future commits.
