riscv: Add the Allwinner SoC family Kconfig option
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.
