[PATCH] arm64: dts: rockchip: Add Beelink A1

[Robin Murphy <robin.murphy@arm.com>]

Beelink A1 is a TV box implementing the higher-end options of the
RK3328 reference design - the DTB from the stock Android firmware is
clearly the "rk3328-box-plus" variant from the Rockchip 3.10 BSP with
minor modifications to accommodate the USB WiFi module and additional
VFD-style LED driver. It features:

- 4GB of 32-bit LPDDR3
- 16GB of HS200 eMMC (newer models with 32GB also exist)
- Realtek RTL8211F phy for gigabit ethernet
- Fn-Link 6221E-UUC module (RealTek RTL8821CU) for 11ac WiFi and Bluetooth 4.2
- HDMI and analog A/V
- 1x USB 3.0 type A host, 1x USB 2.0 type A OTG, 1x micro SD
- IR receiver and a neat little LED clock display.

One question I'm wondering about is whether it's worth pushing the HDMI
and analog codec audio cards down into rk3328.dtsi (as with HDMI audio
on RK3399), since those audio pipelines are internal to the SoC and the
board only really governs whether the outputs are wired up or not.
