PNP: Switch from __check_region() to __request_region()

PNP core is the last user of the __check_region() which has been
deprecated for almost 12 years (since v2.5.54). Replace it with a combo
of __request_region() followed by __release_region().

pnp_check_port() and pnp_check_mem() remain racy after this change.
