tools/power/x86/intel-speed-select: Introduce is_cpu_in_power_domain helper
struct isst_id contains cpu, package and die info, and it can represent
a specific SST power domain.
Introduce is_cpu_in_power_domain() helper to identify if a cpu is in a
specified power_domain.
And cleanup the code to use the new helper.
