All old chip use 0x80 address, but new chip may use another address, so we using pci_find_capability() to get LINK CONTROL address. rtsx_gops.c was removed, we consider to put some common operations to this file, but the actual thing is, only a group of chips are in common ops1, and another group of chips in common ops2, it is hard to decide put which ops into generic ops file.
