net: hibmcge: Add pci table supported in this module

Add pci table supported in this module, and implement pci_driver function
to initialize this driver.

hibmcge is a passthrough network device. Its software runs
on the host side, and the MAC hardware runs on the BMC side
to reduce the host CPU area. The software interacts with the
MAC hardware through the PCIe.
