skylake: provide native gpio functionality
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.
