drivers/tpm: Implement full PPI
Implement the ACPI PPI interface as described in
"TCG PC Client Physical Presence Interface Specification" Version 1.3.
Add a new Kconfig that allows to use the full PPI instead of the stub
version compiled in.
This doesn't add code to execute the PPI request, as that's up to the
payload with graphical UI support.
Tested on GNU/Linux 5.6 using the sysfs interface at:
/sys/class/tpm/tpm0/ppi/
