When a CPU enters an idle state, non-initialized states left in large

The new helper ensures the AMX state is initialized to make the CPU
ready for low-power states. It will be used by the intel idle driver.
What about AVX...AVX512? Are they harmless in that regard?
If so, then the first sentence above is confusing and should clearly
spell out that it's AMX which causes that problem.
