Kconfig: Allow x86 to compress pre-ram stages if not run XIP
On the intel/glkrvp
compressed:
- romstage: 29659
- verstage: 31303
non compressed:
- romstage: 46244
- verstage: 47012
On qemu (with some additional patch to not run XIP)
compressed:
- romstage: 11203
non compressed:
- romstage: 13924
Even with a small romstage the size improvements are substantial,
which should result in a speedup when loading the stage. On the
up/squared loading romstage is sped up by 9ms.
TESTED: successfully boot the up/squared & google/vilboz.
