[coreboot] [PATCH] Disable AC97 modem early on IP1000

This patch disables the AC97 modem via the ICH4 LPC disable function
register early in the boot process. Leaving it enabled was causing resource
allocation problems, making IO read/writes under 0x200 fail. As I found out
by trail and error it has to be done right after the LAN Enable gpio pin is
driven high.

Tested on hardware.
