[PATCH 4/5] platform/x86/amd/pmf: Inline simple helper function of Smart PC TA interfaces

[Rong Zhang]

The Smart PC TA interfaces have a simple and dumb helper function
defined as a global symbol, which is used by other layers and becomes a
symbol against linkage. This bloats the size of the module.

Convert it 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 208 Bytes
(GCC 16 -O2):

     26341      31392       2768      60501 amd-pmf.ko

      text       data        bss      total filename	(after)
     26261      31264       2768      60293 amd-pmf.ko
