Commit Message

From: Daniel Henrique Barboza <dbarboza@ventanamicro.com>

Create a new "i" RISCVCPUMisaExtConfig property that will update
env->misa_ext* with RVI. Instances of cpu->cfg.ext_i and similar are
replaced with riscv_has_ext(env, RVI).

Remove the old "i" property and 'ext_i' from RISCVCPUConfig.
