The old RTL8231 driver integrated the MDIO bus access with the GPIO
control ops, making this driver not very portable to newer platforms.
It depended on the SoC ID instead of the compatible to determine the
MDIO access register, further complicating portability.
A new MFD driver is now available, which offers proper pin config as
well as optional LED support, which can work on any (bitbanged) MDIO
bus. Now that all devices have been migrated, we can drop the old code.

Add pending patches to add RTL8231 support as a MDIO-bus attached
multi-functional device. This includes subdrivers for the pincontrol and
GPIO features, as well as the LED matrix support.
Leave the drivers disabled until required by a device.

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.
