[PATCH v5 2/9] target/riscv: introduce riscv_cpu_cfg()

[Daniel Henrique Barboza <dbarboza@ventanamicro.com>]

We're going to do changes that requires accessing the RISCVCPUConfig
struct from the RISCVCPU, having access only to a CPURISCVState 'env'
pointer. Add a helper to make the code easier to read.
