[PATCH 1/5] platform/x86/amd/pmf: Inline !AMD_PMF_DEBUG stub

[Rong Zhang]

A !CONFIG_AMD_PMF_DEBUG build compiles amd_pmf_dump_ta_inputs() as a
stub. However, the stub is implemented as a global function and becomes
a symbol against linkage. This bloats the size of the module.

As a best practice, convert the stub into a static inline function to
get rid of the overhead of function outlining and linkage, and shrink
the module (!CONFIG_AMD_PMF_DEBUG && CONFIG_AMD_PMF_UTIL_SUPPORT) size
by 65 Bytes (GCC 16 -O2):

      text       data        bss      total filename	(after)
     26781      31636       2768      61185 amd-pmf.ko
