ec/dell: Add support for the SMSC MEC5035
This is required to prevent the EC from shutting down the system after about 15 seconds after being turned on. If the EC doesn't receive a command meaning "CPU OK" it assumes that the processor has failed and flashes a diagnostic code on the keyboard LEDs to indicate this. This also enables the keyboard and trackpad/trackpoint interfaces. Parts of this code were derived from yet-to-be merged code in CB:44975 (ec: Add support for MEC5055 for Dell laptops) written by Iru Cai.
