Hello build bot (Jenkins), Jason Glenesk, Raul Rangel, Marshall Dawson,

I'd like you to reexamine a change. Please visit

soc/amd/*/cpu: handle mp_init_with_smm failure

When the mp_init_with_smm call returns a failure, coreboot can't just
continue with the initialization and boot process due to the system
being in a bad state. Ignoring the failure here would just cause the
boot process failing elsewhere where it may not be obvious that the
failed multi-processor initialization step was the root cause of that.
I'm not 100% sure if calling do_cold_reset or calling die_with_post_code
is the better option here. Calling do_cold_reset likely here would
likely result in a boot-failure loop, so I call die_with_post_code here.
