Revert "soc/intel/{tigerlake,meteorlake}: Check ITBT FW version"
This reverts commit 2e10a6d6f3ec46bcaf75bd066319d51f001be764. Reason for revert: The FW version check is not supported except for ADL platform. Reverted change broke S0ix functionality; the original CL was added as HW W/A for ADL ONLY. BUG=b:306214725 TEST=S0ix cycles on Rex with TBT Device attached.
