tools/power/x86/intel-speed-select: Introduce isst-core-mbox.c
isst-core.c should contain generic core APIs only. Platform specific implementations/configurations should be removed from this file. Introduce isst-core-mbox.c and move all mbox/mmio specific functions to this file. Introduce struct isst_platform_ops which contains a series of callbacks that used by the core APIs but need platform specific implementation. No functional changes are expected.
