gpio_sim_dev_match_fwnode() is a simple wrapper of device_match_fwnode()
Remvoe the unnecessary wrapper.

I think if you move this patch before patch #4 in your series, you only
have to touch this file once.

the precondition of this change is patch #4, it will have building error
if moving it before #4.

actually, we can only do simplifications with benefits brought by #4.

Ah I see. I thought that device_match_fwnode only got the const for the
2nd parameter in patch #4.
