IIM (IC Identification Module) is the fusebox for the mpc5121.
Use #define CONFIG_IIM to turn on the clock for this module
use #define CONFIG_CMD_FUSE to add fusebox commands.
Fusebox commands include the ability to read
the status, read the register cache, override the register cache,
program the fuses and sense them.

MPC5121 rev 2 silicon has a new register for controlling how long
CS is asserted after deassertion of ALE in multiplexed mode.
The default is to assert CS together with ALE. The alternative
is to assert CS (ALEN+1)*LPC_CLK clocks after deassertion of ALE.
The default is wrong for the NOR flash and CPLD on the ADS5121.
This patch turns on the alternative for CS0 (NOR) and CS2 (CPLD)
it does so conditionally based on silicon rev 2.0 or greater.

Adds PCI support for MPC5121
Tested with drivers/net/rtl8139.c
Support is conditional since PCI on old silicon does not work.
ads5121_PCI_config turns on PCI
In this version, condition compilation of PCI code has been moved
from ifdef in board/ads5121/pci.c to board/ads5121/Makefile as
suggested by Jean-Christophe PLAGNIOL-VILLARD

Previous setting cause ips clock to be out of spec. This bug was found by John
