I think this would better fit as a new API in cpu/cpu.h with a signature like
bool cpuHasFeature(const union cpuData *data, const char *feature)
and then used as
*hasHwVirt = cpuHasFeature(data, "vmx") || cpuHasFeature(data, "svm");
Yes, this is going to be terribly inefficient now since each of this calls
will do its own parsing of cpu_map.xml but I'm planning to fix this stupidity.
