* clean up all but two warnings on artecgroup dbe61 

* integrate vsm init into normal x86.c code (so it can run above 1M)
* call void main(unsigned long bist) except void cache_as_ram_main(void)
  on Geode LX (as we do on almost all other platforms now)
* Unify Geode LX MSR setup (will bring most non-working LX targets back
  to life)
