CPUFreq driver need external timer, so add hpet at first. In Loongson 3, only Core-0 can receive external interrupt. As a result, timekeeping cannot absolutely use HPET timer. We use a hybrid solution: Core-0 use HPET as its clock event device, but other cores still use MIPS; clock source is global and doesn't need interrupt, so use HPET.
