ACPI: cpufreq, processor: Detect old BIOS, not supporting CPU freq on a recent CPU.
On Intel CPUs it is rather common and a good hint that BIOSes which do provide
_PPC func, but not the frequencies itself in _PSS function, are old and need
to be updated for CPU freq support.
Tell the user/vendor he has a BIOS/firmware problem.
Make use of FW_BUG interface to give vendors and users the ability to
automatically check with (or let linuxfirmwarekit do that):
dmesg |grep "Firmware Bug"
