[ Upstream commit 5bc148649cf358d0cccf525452a4efbd4bc89a0f ]
Fix the GB-PC2 devicetree. Refer to the schematics of the device for more information.
GB-PC2 devicetree fixes: - Include mt7621.dtsi instead of gbpc1.dts. Add the missing definitions. - Remove gpio-leds node as the system LED is not wired to anywhere on the board and the power LED is directly wired to GND. - Remove uart3 pin group from gpio-pinmux node as it's not used as GPIO. - Use reg 7 for the external phy to be on par with Documentation/devicetree/bindings/net/dsa/mt7530.txt. - Use the status value "okay".
