platform/x86/amd/pmf: Get ambient light information from AMD SFH driver

AMD SFH driver has APIs defined to export the ambient light information;
use this within the PMF driver to send inputs to the PMF TA, so that PMF
driver can enact to the actions coming from the TA.

platform/x86/amd/pmf: Add facility to dump TA inputs

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.

platform/x86/amd/pmf: Add support to get inputs from other subsystems

PMF driver sends changing inputs from each subystem to TA for evaluating
the conditions in the policy binary.

Add initial support of plumbing in the PMF driver for Smart PC to get
information from other subsystems in the kernel.
