The `link_frequency_270_mhz` setting was originally used by the native
graphics init code for Sandy/Ivy Bridge, which is long gone.
The value of this information (which board had it set) is questionable.
The only board that had an LVDS panel and set it to 0 was the ThinkPad
L520, where native graphics init was never reported to work. Also, the
native graphics init only used it for calculations, but never confi-
gured the hardware to use a specific frequency. A look into the docu-
mentation also doesn't reveal any straps that could be used to confi-
gure it.

They are downright useless and result in ACPI errors. So, burn them.
Also, do a minor update to autoport's README about these values.

The processor P_BLK doesn't support throttling. This behaviour could be
emulated with SMM, but instead just update the FADT to indicate no support
for legacy I/O based throttling using P_CNT.
We have _PTC defined in SSDT, which should be used in favour of P_CNT by
ACPI aware OS, so this change has no effect on modern OS.
Drop all occurences of p_cnt_throttling_supported and update autoport
to not generate it any more.
