When riscv_cpu_realize() starts we're guaranteed to have cpu->cfg.ext_N properties updated. The same can't be said about env->misa_ext*, since the user might enable/disable MISA extensions in the command line, and env->misa_ext* won't caught these changes. The current solution is to sync everything at the end of validate_set_extensions(), checking every cpu->cfg.ext_N value to do a set_misa() in the end. The last change we're making in the MISA cfg flags are in the G extension logic, enabling IMAFG if cpu->cfg_ext.g is enabled. Otherwise we're not making any changes in MISA bits ever since realize() starts. There's no reason to postpone misa_ext updates until the end of the validation. Let's do it earlier, during realize(), in a new helper called riscv_cpu_sync_misa_cfg(). If cpu->cfg.ext_g is enabled, do it again by updating env->misa_ext* directly. This is a pre-requisite to allow riscv_cpu_validate_set_extensions() to use riscv_has_ext() instead of cpu->cfg.ext_N to validate the MISA extensions, which is our end goal here.
