soc/intel/xeon_sp/finalize.c: Set BIOS_DONE MSR as applicable

If BIOS_DONE MSR is supported, set it after ReadyToBoot, because FSP
programs certain registers via Notify phase ReadyToBoot and it cannot
be modified by FSP after coreboot has set BIOS_DONE MSR, therefore we
try to set BIOS_DONE MSR as late as possible to avoid this.
