Aswath Govindraju 26f32c32b2 configs: am64x_evm_*_defconfig: Rearrange the components in SRAM to satisfy the limitations for USB DFU boot mode 
For USB DFU boot mode there is a limitation on the load address of boot
images that they have to be less than 0x70001000. Therefore, move the
SPL_TEXT_BASE address to 0x70000000.

Currently ATF is being loaded at 0x70000000, if the SPL is being loaded at
0x70000000 then ATF would overwrite SPL image when loaded. Therefore, move
the location of ATF to a latter location in SRAM, past the SPL image. Also
rearrange the EEPROM and BSS data on top of ATF.

Given below is the placement of various data sections in SRAM
