tools/power/x86/intel-speed-select: Unify TRL levels

TRL supports different levels including SSE/AVX2/AVX512.

Avoid using hardcoded level name and structure fields, so that a loop can
be used to parse each TRL level instead. This reduces several lines of
source code.

No functional changes are expected.
