We are going to use the same core for newer hardware as much as
possible. Hopefully all new SoCs will have GPIO controller which is
based on the same hardware design.

For the existing, unfortunately the hardware differentiates too much
from Sunrisepoint that it does not make much sense to factor them to use
this new core.
