baytrail: configure acpi SCI irq

Browse Source 
Baytrail has a configurable SCI irq. Add support for
properly configuring SCI irq. Note that it is currently
fixed to IRQ9, but the code supports setting it to the
other supported values. The current mainboards using
baytrail defer the madt IRQ override information to the
chipset.

BUG=chrome-os-partner:23505
BRANCH=None
TEST=Built and booted. Noted 'SCI is IRQ9' message.
