tools/power/x86/intel-speed-select: Allow api_version based platform callbacks
Different api_version suggests different kernel driver used and
different interface is used to communication with the hardware.
Allow setting platform specific callbacks based on api_version.
Currently, all platforms with api_version 1 uses Mbox/MMIO interfaces.
No functional changes are expected.
