sec/intel/txt/getsec_enteraccs.S: Save and restore MTRR_DEF_TYPE
This needs to be saved and restored, otherwise the BSP might have an inconsistent MTRR setup with regards to the AP's which results in weird errors and slowdowns in the operating system. TESTED: Fixes booting OCP/Deltalake with Linux 5.8.
