[PATCH v2 6/9] PCI: Rename is_thunderbolt to is_tunneled

[Mario Limonciello]

The `is_thunderbolt` bit has been used to indicate that a PCIe device
contained the Intel VSEC which is used by various parts of the kernel
to change behavior. To later allow usage with USB4 controllers as well,
rename this to `is_tunneled`.
