soc/intel/apollolake: Add handler for SCI
This patch adds the handler to enable bit for gpio_tier1_sci_en.
gpio_tier1_sci_en enables the setting of the GPIO_TIER1_SCI_STS
bit to generate a wake event and/or an SCI or SMI#. We are setting
the bit for gpio_tier1_sci_en from the ASL code as OS clears this bit
if set from BIOS. As per ACPI spec _GPE is defined as the Named
Object that evaluates to either an integer or a package. If _GPE
evaluates to an integer, the value is the bit assignment of the SCI
interrupt within the GPEx_STS register of a GPE block described in
the FADT that the embedded controller will trigger. FADT right now
has no mechanism to acheive the same.
