[coreboot] [PATCH] Fix v3 GeodeLX stack and global variable pointer corruption

Fix v3 GeodeLX stack and global variable pointer corruption.
We had a jump instead of a call to stage1_main in geodelx/stage0.S. That
means all accesses to bist and init_detected were off by 8 bytes and
collided with accesses to the global variable pointer.

Found during my cleanup runs.
