Introduce a new enum pci_reset_mode_t to make the context
of probe argument in reset functions clear and the code
easier to read.
Change the type of probe argument in functions which implement
reset methods from int to pci_reset_mode_t to make the intent clear.
Add a new line in return statement of pci_reset_bus_function.
