mediatek: add v4.19 support

Bump the target to v4.19. Add a patch with additional eth driver
fixes/features that MTK provided aswell as the driver for the new mt7530
switch.

++MediaTek SoCs SPI NAND FLASH interface (SNFI) DT binding
++
++This file documents the device tree bindings for MTK SoCs SPI NAND controller.
++Note that Parallel Nand and SPI NAND is alternative on MTK SoCs.
++
++Required properties:
++- compatible:		should be "mediatek,mt7622-snfi"
++- reg:			base physical address and size of SNFI.
++- interrupts:		interrupts of SNFI.
++- clocks:		SNFI required clocks.
++- clock-names:		SNFI clocks internal names.
++- #address-cells:	NAND chip index, should be 1.
++- #size-cells:		Should be 0.
++
++Example:
++	snfi: spi@1100d000 {
++		compatible = "mediatek,mt7622-snfi";
++		reg = <0 0x1100d000 0 0x1000>;
++		interrupts = <GIC_SPI 96 IRQ_TYPE_LEVEL_LOW>;
++		clocks = <&pericfg CLK_PERI_NFI_PD>,
++			 <&pericfg CLK_PERI_SNFI_PD>;
++		clock-names = "nfi_clk", "spi_clk";
++		ecc-engine = <&bch>;
++		#address-cells = <1>;
++		#size-cells = <0>;
++	};
++
++Subnodes properties:
++- Should use spi-nand framework, see Documentation/devicetree/bindings/mtd/spi-nand.txt
++
++Example:
++&snfi {
++	pinctrl-names = "default";
++	pinctrl-0 = <&serial_nand_pins>;
++	status = "okay";
++
++	spi_nand@0 {
++		#address-cells = <1>;
++		#size-cells = <1>;
++		compatible = "spi-nand";
++		spi-max-frequency = <104000000>;
++		reg = <0>;
++	};
++};
