The current construction for processing SMI GPI events
didn't allow for the mainboard to query the state of a
particular GPI for the snapshotted SMI event. The
skylake part can route GPIs from any (there are design
limitations) GPIO group. Those status and enable registers
are within the GPIO community so one needs to gather
all the possibilities in order to query the state.
The call chain did this:
southbridge_smi_gpi(
clear_alt_smi_status() -> reset_alt_smi_status() ->
print_all_smi_status() -> return 0)
As a replacement the following functions and types are
introduced:
struct gpi_status - represent gpi status.
gpi_status_get() - per gpi query on struct gpi_status
gpi_clear_get_smi_status() - clear and retrieve SMI GPI status
mainboard_smi_gpi_handler() - mainboard handler using gpi_status
Also remove gpio_enable_all_smi() as that construct was never
used, but it also is quite heavy handed in that it would
enable SMI generation for all GPIs.

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().

Some of the field and register names in the power management
code were not reflecting current chipset documentation. While
in there fix 0-sized array in the power_state structure. Lastly,
log the entire STD GPE register for visibility in elog. It reports
as an extension of other GPIO wake events.

In order to provide more clarity on what some of the gpio
functions are doing add a 'gpio_' prefix to the globally
visible functions.
