mmc: sdhci-pci-o2micro: Make some symbols static

Fix the following sparse warning:

drivers/mmc/host/sdhci-pci-o2micro.c:497:6: warning: symbol
'sdhci_pci_o2_set_clock' was not declared. Should it be static?
drivers/mmc/host/sdhci-pci-o2micro.c:512:5: warning: symbol
'sdhci_pci_o2_probe_slot' was not declared. Should it be static?
drivers/mmc/host/sdhci-pci-o2micro.c:581:5: warning: symbol
'sdhci_pci_o2_probe' was not declared. Should it be static?
drivers/mmc/host/sdhci-pci-o2micro.c:786:5: warning: symbol
'sdhci_pci_o2_resume' was not declared. Should it be static?
