Updated the CONFIG_SPL_TEXT_BASE to support secure parts (moving the start address past secure reserved memory and the size of the security certificate that precedes the boot image on secure devices). Updated the related CONFIG_SPL_MAX_SIZE to properly reflect the internal memory actually available on the various device flavors (Common minimum internal RAM guaranteed for various flavors of DRA7xx/AM57xx is 512KB).
