soc/apollolake: add GPIO SMI support
GPIOs which trigger SMIs set the GPIO_SMI_STS status bits in SMI_STS register. This patch also sets the SMI_EN bit in enable register for each community based on GPIOROUTSMI bit in gpio pad. When SMI on a gpio happens status needs to be gathered on gpio number which is done by reading the GPI_SMI_STS and GPI_SMI_EN registers. BUG=chrome-os-partner:54977 TEST=When system is in firmware mode executing the command lidclose from ec console shuts down the system.
