arm64: dts: xilinx: Apply overlays to base dtbs

DT overlays in tree need to be applied to a base DTB to validate they
apply, to run schema checks on them, and to catch any errors at compile
time. Defining the "-dtbs" variable is not enough as the combined DT must
be added to dtbs-y.

zynqmp-sck-kr-g-revA.dtso and zynqmp-sck-kr-g-revB.dtso don't exist, so drop
them.

arm64: xilinx: Use zynqmp prefix for SOM dt overlays

U-Boot is using zynqmp- prefix to compose DT name for board detection

arm64: zynqmp: Add support for Xilinx Kria SOM board

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.

arm64: zynqmp: Add support for zcu102-rev1.1 board

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.

kbuild: handle dtb-y and CONFIG_OF_ALL_DTBS natively in Makefile.lib

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.

kbuild: clean up *.dtb and *.dtb.S patterns from top-level Makefile

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.
