I have removed all generic  PCI definitions from skfbi.h in the next
patch which I have sent, I wanted to keep it organised by sending two
patches

It defines many duplicate definitions in skfbi.h, but only uses one of
them, hence they are removed in the next patch as told by bjorn.
It uses only one generic PCI define in driver code, i.e. PCI_REV_ID, it
has been replaced by PCI_REVISION_ID to make it work with the define
included with uapi/linux/pci_regs.h
