PCI: intel-gw: Add .start_link() callback

Browse source

The pcie-intel-gw driver had no .start_link() callback.  Add one so the
driver works again and does not abort with the following error messages
during probing:

  intel-gw-pcie d1000000.pcie: host bridge /soc/pcie@d1000000 ranges:
  intel-gw-pcie d1000000.pcie:      MEM 0x00dc000000..0x00ddffffff -> 0x00dc000000
