FLASH_START is supposed to point at the memory area where NOR flash are mapped. We currently have an incorrect FLASH_START copied from ar71xx back then and the loader doesn't work under OKLI mode. On ramips, mt7621 has it's flash mapped to 0x1fc00000 and other SoCs uses 0x1c000000. This commit makes FLASH_START a configurable value to handle both cases.
