All generic CPUs call riscv_cpu_add_user_properties(). The 'max' CPU
calls riscv_init_max_cpu_extensions(). Both can be moved to a common
instance_post_init() callback, implemented in riscv_cpu_post_init(),
called by all CPUs. The call order then becomes:
riscv_cpu_init() -> cpu_init() of each CPU -> .instance_post_init()
In the near future riscv_cpu_post_init() will call the init() function
of the current accelerator, providing a hook for KVM and TCG accel
classes to change the init() process of the CPU.

I think we should also remove riscv_cpu_add_user_properties from host
cpu init.

Otherwise, we will enter here for host cpu.

Yes, this seems to be what x86 does, so presumably it'll work for riscv
too.
