Add a disabled node for the auxiliary MDIO bus, used to manage the
RTL8231 expanders. A simple-mfd parent node is added, at the same
(implied) address as the switch@1b000000 node, as the switch drivers
should anyway transistion to MFD subdivices at some point.
Additionally, two pinctrl-single node are added to allow the MDX pins to
be muxed correctly, in case the bootloader leaves these unconfigured.

Add a driver that exposes the auxiliary busses, used for the RTL8231
expanders, as a proper MDIO controller. The device must be instantiated
under an MFD device, so the driver should also be compatible with SoC
managed by an external CPU via SPI.
Leave the driver disabled in builds until required.

Since the start of the Realtek target OpenWrt works with RTL83XX as the
target architecture. Upstream is using MACH_REALTEK_RTL instead. To
simplify further development align that.

Copy files and config from 5.15 kernel version. Because of the big version jump
leave out the patches for now so we can treat them individually later on.
