glados: make EC_SCI_L work

Hardware / Coreboot - Aaron Durbin [chromium.org] - 14 August 2015 08:39 UTC

In order for the EC_SCI_L to work the GPE0 route needs to be set along w/ the GPE event for the EC. As the GPE0 route is dynamic the EC_SCI_GPI needs to be set along with the route so everything lines up. In this case, the GPE0 route is set to the defaults such that GPP_C, GPP_D, and GPP_E are routed to GPE0 block 0, 1, and 2, respectively. This works out for glados because the EC_SCI_L is connected to GPP_E16.

BUG=chrome-os-partner:43778 BRANCH=None TEST=Built and booted glados. The 'acpi' interrupt in /proc/interrupts is incrementing as well as /sys/firmware/acpi/interrupts/gpe50.
