WNDR4700 uboot has an issue with decompressing kernel with default dictionary size (-d23 which is about 8MB).
Limiting lzma dictionary lowers memory footprint and allows device to boot the kernel.
The highest bootable dictonary size is 18, choosing 16 for an extra safety margin.
Kernel size befor and after:
-d23: 2663665 Bytes
-d16: 2892757 Bytes
Kernel size increased by 230kB (9%)
Fixes: FS#3258

The compressed image that the buildbots are building is too large for
the netgear uboot and it crashes and soft-bricks the device.
| Uncompressing Kernel Image ...
| LZMA: uncompress or overwrite error 1 - must RESET board to recover
The whole target likely needs to be switched zImage which is a major
hassle due to powerpc's legacy bootwrapper setup as compared to ARM.
So for now, disable the device.

The DEVICE_DTS variable always matches the device definition name,
just with "_" replaced by "-". Thus, create a DEVICE_DTS definition
in Device/Default and drop all the individual statements.
If necessary in the future, local DEVICE_DTS will still overwrite
that default.

With several subtargets, the image/Makefile becomes crowded after a
while. Many targets have moved their device definitions to $subtarget.mk
files to have them more organized, let's do this here as well.
While at it, also move subtarget-specific build recipes.
