smi: Update mainboard_smi_gpi() to have 32bit argument

With the LynxPoint chipset there are more than 16
possible GPIOs that can trigger an SMI so we need
a mainboard handler that can support this.

There are only a handful of users of this function
so just change them all to use the new prototype.
