tpm: fix raciness of PPI interface lookup
Traversal of the ACPI device tree was not done right. PPI interface
should be looked up only from the ACPI device that is the platform
device for the TPM. This could cause problems with systems with
two TPM chips such as 4th gen Intel systems.
In addition, added the missing license and copyright platter to
the tpm_ppi.c.
