FSP was setting up the TCO registers to be mapped at 0x400.
However, the SMBus initialization in romstage was mapping
its I/O BAR to 0x400 as well. The result seemed to cause the
TCO register to be hidden. However, the board was rebooting in
depthcharge when the SMBus device was enabled from a TCO timeout.
As the TCO timer was halted before the double resource assignment
it's not clear how the TCO was getting re-enabled. In either case,
the current behavior is wrong.
