Moved FspApiReturnStatusReset API to a separate file to eliminate unnecessary inclusion of FspApiReturnStatusReset APIs in driver binary. When the compiler linking the Object files it may not remove all the unused from NASM OBJs. This change is to reorganize the C files to minimize the impact of the NASM behavior resulting is code size reduction. Signed-off-by: Ashraf Ali <ashraf.ali.s@intel.com>
