Len Brown 34d531e640 ACPI: sanity check _PSS frequency to prevent cpufreq crash 
When BIOS SETUP is changed to disable EIST, some BIOS
hand the OS an un-initialized _PSS:

        Name (_PSS, Package (0x06)
        {
            Package (0x06)
            {
                0x80000000,	// frequency [MHz]
                0x80000000,	// power [mW]
                0x80000000,	// latency [us]
                0x80000000,	// BM latency [us]
                0x80000000,	// control
                0x80000000	// status
            },
	    ...

These are outrageous values for frequency,
power and latency, raising the question where to draw
the line between legal and illegal.  We tend to survive
garbage in the power and latency fields, but we can BUG_ON
when garbage is in the frequency field.

Cpufreq multiplies the frequency by 1000 and stores it in a u32 KHz.
So disregard a _PSS with a frequency so large
that it can't be represented by cpufreq.
