soc/intel/apollolake/romstage: Increase size of postcar stack

If you currently activate the measured boot on an Apollo Lake mainboard,
you will run into a stack overflow during postcar. Such a behavior has
already been observed on the Sky Lake platform and a corresponding patch
has been made for this (https://review.coreboot.org/c/coreboot/+/33434).
This issue occurs since the patch for the correct timestamp value in
postcar comes up (https://review.coreboot.org/c/coreboot/+/32726 and
https://review.coreboot.org/c/coreboot/+/32881). By increasing the stack
size for postcar the issue is solved.
