[Qemu-devel] [PULL 23/39] target/riscv: Use env_cpu, env_archcpu

[Richard Henderson <richard.henderson@linaro.org>]

Cleanup in the boilerplate that each target must define.
Replace riscv_env_get_cpu with env_archcpu.  The combination
CPU(riscv_env_get_cpu) should have used ENV_GET_CPU to begin;
use env_cpu now.
