google/reef: Add GPE routing settings
This patch sets the devicetree for gpe0_dw configuration
and also configures the GPIO lines for SCI. EC_SCI_GPI
is configured to proper value.
BUG = chrome-os-partner:53438
TEST = Toggle pch_sci_l from ec console using gpioset command
and see that the sci counter increases in /sys/firmware/acpi/interrupt
and also 9 in /proc/interrupt
