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.
