Inspired by Russell King's patch[1], I found some pci hosts also have the same issue of "reading 32-bits from the command register, modifying the command register, and then writing it back has the effect of clearing any status bits that were indicating at that time" as pointed out by Russell. Fix them by using the pci_generic_config_write.
Another problem is do we need to use proper readb/readw for config read?
