skylake: remove ec_smi_gpio and alt_gp_smi_en

The ec_smi_gpio and alt_gp_smi_en devicetree options are
    goign to be removed. The plan for skylake is to set the
    settings by the mainboard through either gpio pad
    configuration or through helper functions.

Moreover, these values only allow *1* SMI GPIO configuration
    in that the following has to be true:
    alt_gp_smi_en = 1 << (ec_smi_gpio % 24)
    If not, then another gpio(s) from the same group has the
    SMI_EN bit set for it.

Lastly, remove all the subsequent dependencies as they are
    no longer used: enable_alt_smi() and gpio_enable_group().
