[PATCH v4 10/17] platform/x86/amd/pmf: Add facility to dump TA inputs

[Shyam Sundar S K]

PMF driver sends constant inputs to TA which its gets via the other
subsystems in the kernel. To debug certain TA issues knowing what inputs
being sent to TA becomes critical. Add debug facility to the driver which
can isolate Smart PC and TA related issues.

Also, make source_as_str() as non-static function as this helper is
required outside of sps.c file.
