lib/prog_loading: introduce prog_segment_loaded()
In order to not muddle arch vs chipset implementations provide a generic prog_segment_loaded() which calls platform_segment_loaded() and arch_segment_loaded() in that order. This allows the arch variants to live in src/arch while the chipset/platform code can implement their own.
