Subject: [PATCH] tools/power/x86/intel-speed-select: Introduce api_version
helper
In some cases, the output format may be different with different
api_version because of different capabilities or for backward
capabilities reason.
Introduce api_version() to get the api_version of the platform running.
No functional changes are expected.
