soc/intel/tigerlake: Add CrashLog implementation for intel TGL
CrashLog is a diagnostic feature for Intel TGL based platforms. It is meant to capture the state of the platform before a crash. The state of relevant registers is preserved across a warm reset. BUG=None TEST=CrashLog data generated, extracted, processed, decoded sucessfully on delbin.
