ARM: dts: sun9i: Enable i2c3 on A80 Optimus board

i2c3 is exposed on the GPIO extension header. Enable it so we can use it.

Also enable internal pull-ups on the pins, as they don't seem to have
external pull-up resistors.

ARM: dts: sun9i: Add GPIO LEDs for A80 Optimus board

The A80 Optimus board has 3 usable LEDs that are controlled via GPIO.

This patch adds support for 2 of them which are driver by GPIOs in the
main pin controller. The remaining one uses GPIO from the R_PIO
controller, which we don't support yet.

ARM: dts: sun9i: Enable uart4 for A80 Optimus board

The A80 Optimus board exposes uart4 on the GPIO expansion header.
Enable it so we can use it.

Also enable the internal pull-ups, as there doesn't seem to be
external pull-up resistors for pins on the expansion header.
