IntelFsp2Pkg: Remove CarBase and CarSize from FSP_GLOBAL_DATA
CarBase and CarSize in Fsp Global data structure are no longer needed as
Boot loader doesn't pass them to FSP even in case that BL chooses to skip calling
the FspTempRamInit API. In case of FspTempramInit is called, we can use the PCDs
to identify the CarBase and Size. Hence we remove the relevant code.
