nvram: Add option to reset NVRAM to default parameters on every boot
In specific configurations, such as homogeneous supercomputing systems,
changeable NVRAM parameters are more of a liability than a useful tool.
This patch allows a coreboot image to be compiled that will always set
the NVRAM parameters to their default values, reducing maintainance
overhead on large clusters.
