This small series adds support for the Raspberry Pi Zero 2 W.

Changes in V2:
- drop brcmfmac patch, because the driver is already able to handle
  the wifi chip
- improve commit message of DTS patch
- add Robs Acked-by

The Raspberry Pi Zero 2 W mostly bases on the Raspberry Pi Zero W with
the following differences:
* Broadcom BCM2710A1, quad-core 64-bit SoC @ 1 GHz
* Synaptics BCM43436 (reported as BCM43430B0) IEEE 802.11b/g/n wireless LAN

Contrary to the Raspberry Pi 3 boards there is no GPIO expander.

* [PATCH V2 3/3] arm64: dts: broadcom: Add reference to RPi Zero 2 W

This adds a reference to the dts of the Raspberry Pi Zero 2 W,
so we don't need to maintain the content in arm64.
