The intention of 967b6be118e3 ("ar8327: Add workarounds for AR8337
switch") was to remove the register fixups for AR8337. But instead they
were removed for AR8327.

The RGMII RX delay is forced even if the port is used as phy instead of
mac, which results in no package flow at least for one board.

Current version of rtl8366-smi module only supports Realtek switch
managment via two gpio lines. This adds Realtek switch
management via mii_bus. Tested on a Tp-link Archer C2 v1 (Mediatek
SoC mt7620a based)

dts-file configuration should look like this:

rtl8367rb {
	compatible = "realtek,rtl8367b";
	realtek,extif1 = <1 0 1 1 1 1 1 1 2>;
	mii-bus = <&mdio0>;
};

&ethernet {
	status = "okay";
	mtd-mac-address = <&rom 0xf100>;
	pinctrl-names = "default";
	pinctrl-0 = <&rgmii1_pins &rgmii2_pins &mdio_pins>;

	port@5 {
		status = "okay";
		mediatek,fixed-link = <1000 1 1 1>;
		phy-mode = "rgmii";
	};

	mdio0: mdio-bus {
		status = "okay";
	};
};

Remove the compatible without vendor prefix. It is formal wrong and not
used in the tree.

Make the call to of_mdiobus_register() dependant on CONFIG_OF to avoid
pulling in an unwanted dependency on of_mdio.ko.

Since kernel 4.1 bcm47xx_nvram_gpio_pin() is now defined in a global
header and can be safely called even on non-Broadcom platforms.

This change makes b53 look for "robo_reset" on ARCH_BCM_5301X and
slightly simplifies the code.
