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

[Joseph Smith]

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.
