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().

On skylake the GPE0 routing can be dynamically changed to
a particular GPIO group. Provide the ability for the mainboard
to set the route accordingly. If any of the values in the
devicetree are the same the current setting in the PMC register
is used. The GPIO communities need to have matching configuration
for the plumbing to work properly.

It's important to be able to configure the gpio pads at
various stages instead of a single place using FSP. Without
this support there is a lot of duplicated open-coded pad
configuration taking place both within the SoC code and
mainboards.
Current limitation is that all GPIOs are in ACPI mode. i.e.
The HostSW ownership register sets the pad configuration to
only update GPI_GPE_STS, GPI_NMI_STS and/or GPI_SMI_STS. The
GPI_STS update is masked within the GPIO community registers.
