ARM: dts: BCM5301X: Add DT for ASUS RT-AC3100
ASUS RT-AC3100 is ASUS RT-AC88U without the external switch. Move the shared bindings to bcm47094-asus-rt-ac3100.dtsi. Remove the fixed-link node on port@7 as commit ba4aebc ("ARM: dts: BCM5301X: Describe switch ports in the main DTS") states it's not necessary. Replace the copyright notice with an author notice. Rename the model name from Asus to ASUS on bcm47094-asus-rt-ac88u.dts.
