arm: vf610twr: improve memory layout
Currently, the device tree relocation is disabled, likely to keep some DDR3 RAM at the end for Cortex-M4 firmwares. This can be archived using bootm_size, which limits the image processing range of the boot commands. Move the device tree standard load address to a higher address which aligns better with what we are doing on other boards.
