[PATCH 4/4] arm64: dts: rockchip: Add LincStation E1

[Samuel Holland <samuel@sholland.org>]

LincStation E1 is an entry-level NAS device powered by the RK3568B2 SoC
with two 3.5" HDD slots (behind a SATA port multiplier) and two m.2 2280
slots for SSDs (each PCIe 3.0 x1). Other major features include:
 - 4 GiB DRAM / 64 GB eMMC
 - RTL8125 2.5 Gb Ethernet
 - Fn-Link 6222B-SRC Wi-Fi 5 / Bluetooth module
 - 1 USB 5 Gbps + 2 USB high speed ports
 - HDMI output

Each HDD slot provides a GPIO input for disk presence detection and an
output for power control. Since the disks are behind a port multiplier,
there is no way to describe them in the devicetree, so the disk power
is enabled at all times by GPIO hogs, and the detection inputs are used
only as LED triggers.

The board contains several pairs of amber/white LEDs for power, disk,
m.2 slot, and network status. These are configured to use triggers when
possible. The PWM fan uses a relatively aggressive fan curve to keep
the hard disks within a safe temperature range. It may benefit from
further tuning.

The pinhole reset button is multiplexed between the SoC reset pin and
an ADC input. The mux is configured here to drive the SoC reset pin, as
this works reliably without polling by software. The adc-keys
description is included for use by a devicetree overlay if desired.
