soc/intel/meteorlake: Add `.final` to check FSP reset pending request
This patch adds an API to check FSP reset pending requests. This information is useful to understand if FSP would like boot firmware to issue any reset to complete the silicon initialization. As per recent debug it has been found that, FSP is accumulating all platform resets and executing a single reset from FSP Notify Phase. As coreboot skipped calling into the FSP Notify APIs hence, it might have missed the scope to issue the platform reset. BUG=b:282266168 TEST=Able to build and boot google/rex and able to detect FSP reset pending request.
