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.

This patch adds support of vendor sub directories for dtb files.
Subdirectories can be specified in $(dts-dirs). Kbuild traverses over
all directories while building and installing dtb files. The directory
tree is also reflected in the install path.

Add dtb files to build targets and let kbuild handle them. Thus,
special dtbs rules can be removed. This eases Makefiles and the
implementation of the support of vendor dtb subdirectories.

Move dtbs install rules to Makefile.dtbinst. This change is needed to
implement support for dts vendor subdirs. The change makes Makefiles
easier and smaller as no longer the dtbs_install rule needs to be
defined. Another advantage is that install goals are not encoded in
targets anymore (%.dtb_dtbinst_).

This adds the dtbs_install make target to arm64. The target has been
introduced already to arch/arm with the following commit:

 f4d4ffc0 kbuild: dtbs_install: new make target

Implementation for arm64 is the same as for arm.

With 'dtbs_install' all config enabled dtb files are installed to
either the INSTALL_DTBS_PATH directory or the default location:

 $INSTALL_PATH/dtbs/$KERNELRELEASE

if_changed (used by the *.dts->*.dtc rule) rebuilds files if they aren't
contained in $(targets). (make V=2 indicates this). Add $(dtb-y) to
$(targets) to prevent *.dtb from always being rebuilt. Note

This fixes a regression introduced by the .dtb rule rework in da4cbc6d
"arm64: use new common dtc rule", although since arm64 doesn't actually
have any *.dts yet, this isn't a critical issue.

The current rules have the .dtb files build in a different directory
from the .dts files. This patch changes arm64 to use the generic dtb
rule which builds .dtb files in the same directory as the source .dts.

This requires moving parts of arch/arm64/boot/Makefile into newly created
arch/arm64/boot/dts/Makefile, and updating arch/arm64/Makefile to call the
new Makefile.
