This patch is from 2009-10-20

Convert all DEBUG_SMBUS, DEBUG_SMI, and DEBUG_RAM_SETUP custom and
local #defines into globally configurable kconfig options (and Options.lb
options for as long as newconfig still exists) which can be enabled
by the user in the "Debugging" menu.

The respective menu items only appear if a board is selected where the
chipset code actually provides such additional DEBUG output.

All three variables default to 0 / off for now.

Also, drop a small chunk of dead/useless code in the
src/northbridge/via/cn700/raminit.c file, which would otherwise break
compilation.

Reworked to still apply to trunk, added X86EMU_DEBUG (and make the x86emu/yabel
code only work printf instead of a redefined version of printk and
