Allwinner manufactures the sunxi family of application processors. This includes the "sun8i" series of ARMv7 SoCs, the "sun50i" series of ARMv8 SoCs, and now the "sun20i" series of 64-bit RISC-V SoCs.
The first SoC in the sun20i series is D1, containing a single T-HEAD C906 core. D1s is a low-pin-count variant of D1 with co-packaged DRAM.
Most peripherals are shared across the entire chip family. In fact, the ARMv7 T113 SoC is pin-compatible and almost entirely register-compatible with the D1s.
This means many existing device drivers can be reused. To facilitate this reuse, name the symbol ARCH_SUNXI, since that is what the existing drivers have as their dependency.

Changes in v4: - Drop the now-redundant 'select SIFIVE_PLIC' - Rebase on v6.2-rc1 + soc2arch-immutable
Changes in v3: - ARCH_SUNXI depends on MMU && !XIP_KERNEL
Changes in v2: - Sort Kconfig as if we had done s/SOC_/ARCH_/ for future-proofing
