mpc85xx: convert TL-WDR4900 v1 to simpleImage
Converts the TP-Link WDR4900 v1 to use the simpleImage in the hopes of prolonging the life of the device. While at it, the patch makes the fdt.bin an ARTIFACT and sets the KERNEL_SIZE to 2684 KiB as a precaution since the stock u-boot is using a fixed kernel size. Note: Give the image some time, it will take much longer to extract and boot.
