soc/intel/apollolake: Do not re-save BIST result

BIST result is already stored by arch/x86/bootblock_ctr0.S in
mm0. Also, eax does not contain BIST result by the time control
reaches bootblock_pre_c_entry. bootblock_crt0.S saves timestamp in mm2
which was being overwritten here. Thus, remove the saving of BIST
result from SoC code.
