elfloader: properly handle PHDRs that span flash pages

Rework the previous hack to properly handle PHDRs that span flash
pages and require loading. This should support any ELF image up to the
maximum configured number of PHDRs (30); in particular this handles the
cheriot-rtos test suite firmware image that has 27 PHDRs..
