soc/intel/meteorlake: Allow possible options for MP Init
Ported back from commit ceaf9d116949da68aa9c ("soc/intel/alderlake: Allow possible options for MP Init") This patch creates choice that lists all possible options to perform MP Init as below for Intel Meteor Lake platform: 1. MTL_USE_FSP_MP_INIT: Allow coreboot to bring APs from reset and FSP runs feature programming based and selects MP_SERVICES_PPI_V2 config. 2. MTL_USE_COREBOOT_MP_INIT: Allow coreboot to perform MP Init (both AP init and feature programming) using native implementation. Additionally, selects required RELOAD_MICROCODE_PATCH when coreboot is expected to run MP Init. Refactor SoC code to allow required FSP UPD override based on selected MP Init option. Additionally, added `FIXME` comment to ensure Intel MTL FSP can bring back SkipMpInit UPD in MTL to let coreboot override this UPD and ensure independent MP Init flow. BUG=b:219053812 TEST=Able to build google/rex.
