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.
