[PATCH 0/4] target/riscv: Some CPURISCVState related cleanup and simplification

[Weiwei Li <liweiwei@iscas.ac.cn>]

The patchset tries to:

- Use riscv_cpu_cfg(env) instead of env_archcpu().cfg.
- Use env_archcpu() to get RISCVCPU pointer from env directly
- Use CPURISCVState as argument directly in riscv_cpu_update_mip and riscv_timer_write_timecmp to simplify type conversion
- Remove RISCVCPU argument of riscv_csrrw_check, and get cfg infomation from CPURISCVState directly

The port is available here:
