mb/google/brya/variants/felwinter: Enable TBT PCIe Root Port 0
The TBT device can't be recognized after we re-plug it at DB type-c
port. Intel found that tbt_pcie_rp0 has mapping error after each
re-plug. From Intel suggestion, we enable TBT PCIe RP0 to fix this
problem and take this as short term solution. Intel will implement
re-mapping mechanism in ACPI for long term solution.
