riscv: dts: allwinner: Add ClockworkPi and DevTerm devicetrees

Browse Source 
Clockwork Tech manufactures several SoMs for their RasPi CM3-compatible
"ClockworkPi" mainboard. Their R-01 SoM features the Allwinner D1 SoC.
The R-01 contains only the CPU, DRAM, and always-on voltage regulation;
it does not merit a separate devicetree.

The ClockworkPi mainboard features analog audio, a MIPI-DSI panel, USB
host and peripheral ports, an Ampak AP6256 WiFi/Bluetooth module, and an
X-Powers AXP228 PMIC for managing a Li-ion battery.

The DevTerm is a complete system which extends the ClockworkPi mainboard
with a MIPI-DSI panel and a pair of expansion boards. These expansion
boards provide a fan, a USB keyboard, speakers, and a thermal printer.
