drivers/intel/fsp2_0: Add support for MP services2 PPI
Add support for MP services2 PPIs, which is slight modification over MP services 1 PPIs. A new API StartupAllCPUs have been added to allow running a task on BSP and all APs. Also the EFI_PEI_SERVICES parameter has been removed from all MP PPI APIs. This implementation also selects the respective MP services PPI version supported for SoCs BUG=b:169196864 Change-Id: Id74baf17fb90147d229c78be90268fdc3ec1badc Signed-off-by: Aamir Bohra <aamir.bohra@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/49474 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
