[IMP] point_of_sale, pos_adyen, pos_mercury: payment terminal per method

For now when you are using payment terminals in the point of sale, you
have different way to configure payment temrminals, for the IOT, you
have to select the payment terminal in the pos config, and for adyen and
ventiv you have to configure them in the payment method.

So we've modified it to always configure payment terminal on payment
mehthod, and not on the pos config anymore, with iot you'll be able to
select the specific device you want to use, even if it is not on the iot
box set on the pos config.
