Convert linker scripts and arc_mpu_regions.c setup to use new devicetree.h macros to extract the base address and size of the various memory regions (DDR, SRAM, FLASH, DCCM, ICCM). We also remove the scaling up and down since DT_REG_SIZE() returns the value in bytes. Signed-off-by: Kumar Gala <kumar.gala@linaro.org>
