There are couple of revisions of SOMs (k26) and associated carrier cards
(kv260).
SOM itself has two major versions:
sm-k26 - SOM with EMMC
smk-k26 - SOM without EMMC used on starter kit with preprogrammed firmware
in QSPI.
SOMs are describing only devices available on the SOM or connections which
are described in specification (for example UART, fwuen).
When SOM boots out of QSPI it uses limited number of peripherals defined by
the specification and present in sm(k)-k26 dtses.
Then a carrier card (CC) detection is happening and DT overlay is applied
to brings new functionality. That's why DT overlays are used. The name is
composed together with SOM name and CC name that's why DT overlays with
these names are generated to make sure they can be used together.

zcu102 rev1.1 compare to rev1.0 is using by default different DDR memory
which requires different configuration. The reason for adding this file to
Linux kernel is that U-Boot fdtfile variable is composed based on board
revision (in eeprom) and dtb file should exist in standard distibutions for
passing it to Linux kernel.

Xilinx ZynqMP zcu104 revC and newer board revisions have different i2c
structure compare to revA. The rest of the board is the same from software
perspective.
Also enable DMAs and QSPI.

Avnet Ultra96 rev1 board is commercialized Xilinx zcu100 revC/D
internal board. The patch is reusing zcu100 revC files but changing
model description and compatible strings which are used for example by
libmraa.

If CONFIG_OF_ALL_DTBS is enabled, "make ARCH=arm64 dtbs" compiles each
DTB twice; one from arch/arm64/boot/dts/*/Makefile and the other from
the dtb-$(CONFIG_OF_ALL_DTBS) line in arch/arm64/boot/dts/Makefile.
It could be a race problem when building DTBS in parallel.
Another minor issue is CONFIG_OF_ALL_DTBS covers only *.dts in vendor
sub-directories, so this broke when Broadcom added one more hierarchy
in arch/arm64/boot/dts/broadcom/<soc>/.
One idea to fix the issues in a clean way is to move DTB handling
to Kbuild core scripts. Makefile.dtbinst already recognizes dtb-y
natively, so it should not hurt to do so.
Add $(dtb-y) to extra-y, and $(dtb-) as well if CONFIG_OF_ALL_DTBS is
enabled. All clutter things in Makefiles go away.
As a bonus clean-up, I also removed dts-dirs. Just use subdir-y
directly to traverse sub-directories.

We need to add "clean-files" in Makfiles to clean up DT blobs, but we
often miss to do so.
Since there are no source files that end with .dtb or .dtb.S, so we
can clean-up those files from the top-level Makefile.
