The IBM Everest and Rainier systems have a GPIO line that goes to the
power supplies. It has a dual function: 1) Fans Full Speed, and 2) Sync
input history.

The state of this GPIO determines whether a factory reset has been
requested. If a physical switch is used, it can be high or low. During boot,
the software checks and records the state of this switch. If it is different
than the previous recorded state, then the read-write portions of memory are
reformatted.

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. Switch to KCS 3 which has a different reset behaviour.

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.
