To be able to tunnel non-PCIe traffic, separate tunnel functionality into generic and PCIe specific parts. Rename struct tb_pci_tunnel to tb_tunnel, and make it hold an array of paths instead of just two. Update all the tunneling functions to take this structure as parameter. We also move tb_pci_port_active() to switch.c (and rename it) where we will be keeping all port and switch related functions. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
