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.
