drivers/intel/fsp2_0: Add Kconfig option to control MBP HOB creation
This patch adds a new Kconfig option `FSP_PUBLISH_MBP_HOB` to control the creation of the ME_BIOS_PAYLOAD_HOB (MBP HOB) by FSP. Disabling this option can improve boot time on platforms that do not utilize the MBP HOB, such as ChromeOS devices. The option is disabled by default on ChromeOS and enabled by default on other platforms. On ADL-P based platforms, this option is forced to be enabled as ADL-P FSP relies on MBP HOB for ChipsetInit version for ChipsetInit sync. Removed SoC specific implementation of `FSP_PUBLISH_MBP_HOB` config from MTL and TGL config file. TEST=Tested on ADL-P and ADL-N platforms. Verified that MBP HOB is created when `FSP_PUBLISH_MBP_HOB` is enabled and not created when it is disabled. Also verified that the system boots successfully in both cases.
