mb/intel/kblrvp: Disable I2C #4 and #5 on PCH-H
The I2C #4 and I2C #5 devices do not exist on PCH-H. Disable the devices
using the PCH-H variants' overridetrees (the base devicetree enables I2C
#4), set the `SerialIoDevMode` entries to `PchSerialIoDisabled` and drop
inapplicable I2C #4 voltage settings.
