SRU Justification
[Impact]
* Microsoft indicated that "UBUNTU: SAUCE: clocksource: hyper-v: Use InvariantTSC and enable TSC page for a TDX VM without paravisor" can be removed since an equivalent patch (7f828d5fff7d: "clocksource: hyper-v: Use lapic timer in a TDX VM without paravisor") has been upstream as of 6.10
[Fix]
* 1 clean revert
[Test Plan]
* Compile tested
[Regression potential]
* Little regression potential as this gets us closer to upstream, is isolated, and is confirmed by Microsoft
