Correct to point to the base location of the download image area. Increase CONFIG_SPL_TEXT_BASE to account for this scratch area being used. As part of correcting these tests, make use of the fact that we've always been placing our stack outside of the download image area (which is fine, once the downloaded image is run, ROM is gone) so correct the max size test to be the ROM defined top of the download area to where we link/load at.

Only OMAP4+ has the omap_hw_init_context function so add ifdefs to not call it on am33xx/ti81xx. Call save_omap_boot_params from s_init on am33xx/ti81xx boards.
