For the old AMD processor (family < 0x17), cpupower will call the
amd_pci_get_num_boost_states function, but for the non-root user
pci_read_byte function (implementation comes from the psutil library),
val will be set to 0xff, indicating that there is no read function
callback. At this time, the original logic will set the cpupower turbo
active state to yes. This is an obvious issue~
Reproduce procedure:
