tools: kwboot: Patch destination address to DDR area for SPI image
SPI/NOR kwbimage may have destination address set to 0xFFFFFFFF, which means that the image is not downloaded to DDR but rather it is executed directly from SPI/NOR. In this case execution address is set to SPI/NOR area. When patching image to UART type, change destination and execution addresses from SPI/NOR XIP area to DDR area 0x00800000 (which is default for A38x).
