Subject: [PATCH v4 net-next 10/10] mips: dts: ralink: mt7621: add GB-PC2 LEDs

Add the missing LEDs for GB-PC2. The ethblack-green, ethblue-green, power
and system LEDs weren't added previously, because they don't exist on the
device schematics. Tests on a GB-PC2 by me and Petr proved otherwise.

The i2c bus cannot be used on GB-PC2 as its pins are wired to LEDs instead,
and GB-PC1 does not use it. Therefore, do not enable it on both devices.
