Lukas Wunner 5d03847175 thunderbolt: Use is_pciehp instead of is_hotplug_bridge 
The thunderbolt driver sets up device link dependencies from hotplug ports
to the Host Router (aka Native Host Interface, NHI).  When resuming from
system sleep, this allows the Host Router to re-establish tunnels to
attached Thunderbolt devices before the hotplug ports resume.

To identify the hotplug ports, the driver utilizes the is_hotplug_bridge
flag which also encompasses ACPI slots handled by the ACPI hotplug driver.

Thunderbolt hotplug ports are always Hot-Plug Capable PCIe ports, so it is
more apt to identify them with the is_pciehp flag.

Similarly, hotplug ports on older Thunderbolt controllers have broken MSI
support and are quirked to use legacy INTx interrupts instead.  The quirk
identifies them with is_hotplug_bridge, even though all affected ports are
also matched by is_pciehp.  So use is_pciehp here as well.
