The MCTP LPC driver was loaded by hacking up the compatible in the devicetree node for KCS 4. With the introduction of the raw KCS driver this hack is no-longer required. Use the regular compatible string for KCS 4 and configure the appropriate SerIRQ. The reset state of the status bits on KCS 4 is inappropriate for the MCTP LPC binding.

Add the power-config-full-load described in: https://github.com/openbmc/docs/blob/master/designs/device-tree-gpio-naming.md#power-config-full-load The power-config-full-load gpio is designed to be used to specify how many power supplies the system should have, in rainier it is 2 or 4. If enough power supplies fail so that the system no longer has redundancy (no longer n+1), the hardware will signal to the Onboard Chip Controller that the system may be oversubscribed, and performance may need to be reduced so the system can maintain it's powered on state.
