Instead of having different structures for loading
ramstage and payload align to using struct prog.
This also removes arch_payload_run() in favor of
the prog_run() interface.

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.

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.

Instead of having 2 different functions to call when a program
is loaded provide a single callback with flags parameter. The
previous callbacks for cache management routines did this:
for_each_program_segment:
arch_program_segment_loaded(start, size);
arch_program_loaded();
Now, use one callback instead:
for_each_program_segment:
arch_segment_loaded(start, size, SEG_FINAL?);

There's no need to keep track of struct payload within
the boot state machine. It is completely contained within
the payload loader module.

The functions related to caching ramstage were in cbfs.h.
Now that the loading code is separate move those declarations
to the common program_loading.h.

Two weak functions were added so that architecture specific operations
on each segment of payload or stage can be performed.
Each architecture must define its own operations, otherwise the
behavior will default to do-nothing functions.
This patch has been updated by to fit more in line with
how program loading is currently being done. The API is the
same as the original, but all call sites to stages/payloads
have been updated. This is known to break any archs that use
rmodule loading that needs cache maintenance. That will be fixed
in a forthcoming patch. Also, the vboot paths are left as is
for easier upstreaming of the rest of the vboot patches.

Provide a common run_romstage() function to be used by
bootblocks to load and run romstage. This is similar to
run_ramstage() in that it provides a single entry point
for doing the necessary work of loading and running romstage.

Instead of two headers for payload and ramstage loading
combine the 2 files into one. This also allows for easier
refactoring by keeping header files consistent.
