[PATCH v2 4/4] [DO NOT MERGE] arm64: dts: allwinner: pinephone: Add keyboard

[Samuel Holland <samuel@sholland.org>]

The official PinePhone keyboard accessory connects to the phone's POGO
pins for I2C and interrupts. It has an Injoinic IP5209 power bank IC
connected to the keyboard's internal I2C bus.
