44f89614c6 apm821xx: disable MX60(W) due to kernel size
disables the MX60(W) from being built by the builders for now.
But there's an effort to bring it back:

7a6a349445 apm821xx: WNDAP620 + WNDAP660: reorganize partitions for 5.10
Due to 5.10 increased kernel size, the current 4MiB-ish kernel
partition got too small. Luckily, netgear's uboot environment
is setup to read 0x60000 bytes from the kernel partition location.

... While at it: also do some cleanups in the DTS in there.

The original (re-)installation described in
commit d82d84694e ("apm821xx: add support for the Netgear WNDAP620 and WNDAP660")
seemed to be still working for now. What I noticed though
is that the bigger initramfs images needed to use a different
destination address (1000000) to prevent it overwriting
itself during decompression. i.e:
 # tftp 1000000 openwrt-...-wndap620-initramfs-kernel.bin
 # bootm

However, in case of the WNDAP620+660 the factory.img image can be
written directly to the flash through uboot.

1941ac06f0 apm821xx: Netgear WNDR4700 limit kernel lzma dictionary
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

caa6ada969 apm821xx: disable WNDR4700 5.4 image
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.

eff0a0e39e apm821xx: derive DEVICE_DTS from device name
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.

11db48f89a apm821xx: move device definitions to subfiles
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.
