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.

Add initial device trees for the RTD1295 SoC and the Zidoo X9S TV box.
The CPUs lack the enable-method property because the vendor device tree
uses a custom "rtk-spin-table" method and "psci" did not appear to work.
The UARTs lack the interrupts properties because the vendor device tree
connects them to a custom interrupt controller. earlycon works without.
A list of memory reservations is adopted from v1.2.11 vendor device tree:
0x02200000 can be used for an initrd, 0x01b00000 is audio-related;
ion-related 0x02600000, 0x02c00000 and 0x11000000 are left out;
0x10000000 is used for sharing the U-Boot environment; others remain
to be investigated.
