nb/intel/nehalem: Fix smashed stack in romstage

Stack smashing was detected during raminit when not loading from MRC.
Adding CAR_GLOBAL to a struct inside raminit was suggested in
https://mail.coreboot.org/pipermail/coreboot/2018-May/086677.html in
order to fix the problem.
Adding CAR_GLOBAL to the ram timings variable solves the issue (adding
it to the ram_training or raminfo struct had no effect).
This is just a workaround and might need a proper fix in the future.

Tested on Lenovo X201i with 2+2 and 4+4 GB RAM.
