The flush of the BL33 image is already handled in load_image().
For ED1/EV1 boards, this extra flush was also doing nothing, as for
those boards image_base + image_max_size = 0x100000000, which overflows
an u32, and 0 was used.
This flush is now replaced with a correct invalidation of the cache
directly in io_stm32image.
