Some cleanups for the rtc-cmos probe logic: - Claim i/o ports with request_region() not request_resource(), for better coexistence betwen platform and pnp bus glues. - Claim those ports earlier, to help work around procfs bugs (it allows duplicate names, like /proc/driver/rtc). - Fix some glitches in cleanup code, notably a cut'n'paste-o where the i/o port region might not get released during cleanup after a probe fault. And some comment clarifications, including noting that this code must work with PNPBIOS not just PNPACPI..
