V4L/DVB (9110): cx18: Add default behavior of checking and retrying PCI MMIO accesses
cx18: Add default behavior of checking and retrying PCI MMIO accesses. The concept of checking and retrying PCI MMIO accesses for better reliability in older motherboards was suggested by Steve Toth <stoth@linuxtv.org>. This change implements MMIO retries and the retry_mmio module parameter that is enabled by default. Limited experiments have shown this is more reliable than the mmio_ndelay parameter. mmio_ndelay has insignificant effect with retries enabled.
