Current code uses devm_regulator_register() so the we don't need to explicitly
call regulator_unregister() in .remove.
And then we don't need to save rdev pointer to tps->rdev[id].

I'm sorry that I just found I CC wrong developers in my previous mail.
So here is a resend.

This is a DT-only driver, so make it depend on OF and remove of_match_ptr in
the code.
