cr50: add a factory config space
Add a 64 bit write once factory config space to info1. If the factory
has something they want to configure, they can use part of the space to
store that configration.
Right now nothing in cr50 uses the factory config space. If we need to
modify cr50 behavior based on the space value, we can add functionality
later. The factory just needs to set the bit in the factory config.
