Remove this. Dynamic allocation should be fine, if you're using the
new userspace ABI like tools/gpio/* or libgpiod and only that and in-kernel
consumers, dynamic numbers are just fine.

If you have old sysfs userspace that you need to support using the
global GPIO numberspace, please look into ways to phase that out.
