program loading: introduce struct prog
The struct prog serves as way to consolidate program loading. This abstraction can be used to perform more complicated execution paths such as running a program on a separate CPU after it has been loaded. Currently t124 and t132 need to do that in the boot path. Follow on patches will allow the platform to decide how to execute a particular program. Note: the vboot path is largely untouched because it's already broken in the coreboot.org tree. After getting all the necessary patches pushed then vboot will be fixed.
