Add optional local-bd-address property which is a 6-byte array
storing the assigned BD address. Since having a unique BD address
is critical, a per-device property value should be allocated.

Use integers (reg property) to tell the number of the LED to the driver
instead of the node name. While both of these approaches are currently
used by the LED bindings, using integers will require less driver changes
for ACPI support. Additionally, it will make possible LED naming using
chip and LED node names, effectively making the label property most useful
for human-readable names only.

The watchdog IP block on Meson8 and Meson8m2 is already supported by the
existing meson-wdt driver. Meson8 uses the same register bits as Meson6,
while the newer Meson8m2 SoC uses the same register bits as Meson8b.

Currently watchdog support on Meson8 SoC already works because
meson8.dtsi simply uses the "amlogic,meson6-wdt" compatible. Adding a
separate compatible for Meson8 makes this more explicit though.

Compared to the old xrx200_phy_fw driver the new version has multiple
enhancements. The name of the firmware files does not have to be added
to all .dts files anymore - one now configures the GPHY mode (FE or GE)
instead. Each GPHY can now also boot separate firmware (thus mixing of
GE and FE GPHYs is now possible).
The new implementation is based on the RCU syscon-mfd and uses the
reeset_controller framework instead of raw RCU register reads/writes.

The reset controllers (on xRX200 and newer SoCs have two of them) are
provided by the RCU module. This was initially implemented as a simple
reset controller. However, the RCU module provides more functionality
(ethernet GPHYs, USB PHY, etc.), which makes it a MFD device.
The old reset controller driver implementation from
arch/mips/lantiq/xway/reset.c did not honor this fact.

For some devices the request and the status bits are different.
