Christian Lamparter 1e41de2f48 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.

[tested for 4.14/4.19]
