mips: implement arch_segment_loaded callback
This change adds cache management after loading stages. Before jumping to a new stage we should flush the data caches to memory and invalidate instruction cache. After all segments are loaded CBFS cache is also flushed. With this change all stages of coreboot are now executed successfully. This was tested on Pistachio bring up board, also known as Urara.
