riscv: dts: allwinner: Add the D1/D1s SoC devicetree

D1 (aka D1-H), D1s (aka F133), R528, and T113 are a family of SoCs based
on a single die, or at a pair of dies derived from the same design.

D1 and D1s contain a single T-HEAD Xuantie C906 CPU, whereas R528 and
T113 contain a pair of Cortex-A7's. D1 and R528 are the full version of
the chip with a BGA package, whereas D1s and T113 are low-pin-count QFP
variants.

Because the original design supported both ARM and RISC-V CPUs, some
peripherals are duplicated. In addition, all variants except D1s contain
a HiFi 4 DSP with its own set of peripherals.

The devicetrees are organized to minimize duplication:
 - Common perhiperals are described in sunxi-d1s-t113.dtsi
 - DSP-related peripherals are described in sunxi-d1-t113.dtsi
 - RISC-V specific hardware is described in sun20i-d1s.dtsi
 - Functionality unique to the D1 variant is described in sun20i-d1.dtsi

The SOC_PERIPHERAL_IRQ macro handles the different #interrupt-cells
values between the ARM (GIC) and RISC-V (PLIC) versions of the SoC.
