IntelFsp2Pkg/FspSecCore: Use UefiCpuLib.
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2825
UefiCpuLib has API InitializeFloatingPointUnits.
Remove internal copy of InitializeFloatingPointUnits
in FspSecCoreM, use UefiCpuLib API.
This change also avoid later potential conflict when
use UefiCpuLib for FspSecCoreM module.
