lspci: Add TEE-IO extended capability bit

PCIe r6.1, sec 7.5.3.3 defines "TEE-IO Supported" in the PCI Express Device
Capabilities Register which indicates that the function implements
the TEE-IO functionality as described by the TEE Device Interface Security
Protocol (TDISP, PCIe r6.1, chapter 11).

tests/cap-ide is an example of such device.
