baskingridge: zero out alt_gp_smi_en in devicetree

The baskingridge has a non-zero alt_gp_smi_en value in the
    devicetree.cb file. It has just to be determined which GPI
    pins should trigger an SMI on basking ridge. Without this change
    the board would hang during boot (presumably through a SMI flood).

No more hangs once the value is zero.
