program loading: add prog_run() function
The prog_run() function abstracts away what is required for running a given program. Within it, there are 2 calls: 1. platform_prog_run() and 2. arch_prog_run(). The platform_prog_run() allows for a chipset to intercept a program that will be run. This allows for CPU switching as currently needed in t124 and t132.
