This adds basic BayTrail platform ASL files. They are intended to be included in dsdt.asl of any board that is based on this platform. Note: ACPI mode support for GPIO/LPSS/SCC/LPE are not supported for now. They will be added in the future. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
