From: Zijun Hu <quic_zijuhu@quicinc.com>

Simplify devm_ioport_unmap() implementation by dedicated API
devres_release(), compared with current solution, namely
ioport_unmap() + devres_destroy(), devres_release() has below advantages:

- it is simpler if devm_ioport_unmap()'s parameter @addr was ever
  returned by devm_ioport_map().

- it can avoid unnecessary ioport_unmap(@addr) if @addr was not
  ever returned by devm_ioport_map().
