On some platforms the HFSTS4 bit 19 does not indicate active PTT.
Instead of ME HFSTS4, use TXT FTIF register to check active TPM for
the current boot. Discrete TPM shall be deactivated when PTT is
enabled so this always should return true value of PTT state.
Leave the old method for backwards compatibility if TXT FTIF would not
be applicable for older microarchitectures.

Add functionality such that the FPMCU is power cycled and has its reset
sequenced on boot.
This has been added such that we do not need to update the bootblock.
We are required to do this as bootblock exists in read-only flash for
devices that have already been manufactured and so have no method of
updating the sequencing there.
Power remains off during coreboot (after briefly being turned on in the
unchangeable bootblock).
Once control is handed over to the Kernel, it takes care of sequencing
the power and reset appropriately and ensures the FPMCU is unpowered for
>200ms on boot.

Historically, ChromeOS devices have worked around the problem of OEMs
using several different parts for touchpads/touchscreens by using a
ChromeOS kernel-specific 'probed' flag (rejected by the upstream kernel)
to indicate that the device may or may not be present, and that the
driver should probe to confirm device presence.
Since c636142b, coreboot now supports detection for i2c devices at
runtime when creating the device entries for the ACPI/SSDT tables,
rendering the 'probed' flag obsolete for touchpads. Switch all touchpads
in the tree from using the 'probed' flag to the 'detect' flag.
Touchscreens require more involved power sequencing, which will be done
at some future time, after which they will switch over as well.
TEST: build/boot at least one variant for each baseboard in the tree.
Verify touchpad works under Linux and Windows. Verify only a single
touchpad device is present in the ACPI tables.
