glados: make EC_SCI_L work
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.
