CB:41106 revealed that mb/intel/cedarisland already sets FSP-S UPD (see
CB:40735) while the required includes are still missing in CPX. Buildbot
did not fail because `ramstage.c` never was (implicitly) included.
Fix this problem by making SKX/CPX share a common ramstage header for
now by moving the one from SKX.
Test: Build cedarisland_crb
