Add U-Boot support for Milk-V Duo 256M.
This board has a different SoC compared to the Milk-V Duo 64M, it uses
the Sophgo SG2002 instead of the Sophgo CV1800B. Both SoCs share many
common IP blocks, so this board reuses the existing cv1800b CPU support.
The board shares the same 'board.c' with Milk-V Duo 64MB (CV1800B), so
use the same file for now.

Adopt the kernel device tree directly from
dts/upstream/src/riscv/spacemit/k1-bananapi-f3.dts instead of carrying
a forked copy under arch/riscv/dts/.
The U-Boot-only overlay k1-bananapi-f3-u-boot.dtsi carries the binman
description and a memory@0 node, since the upstream kernel DT has no
memory node (RAM is filled in by the bootloader).

The commit d92fdb60677b ("binman: Add option for pointing to separate

not the be the part of DT for OS.
The main reason is that binman is not passing dt schema validation that's
why want to keep it separated.

Add initial dts for K230-CanMV powered by Canaan Kendryte K230 SoC,
which has two RISC-V C908 cores, a big core with vector 1.0 extension
and a small core without vector extension.
This patch is basically comes from Linux Kernel [1] and it assumes
u-boot is running on the big core. Additionally, bootctl and reboot nodes
are added to support sysreset [2] and an clk_dummy node is added to
satisfy dependencies for usb [3].
Currently, u-boot is booted by the vendor's u-boot-spl. To meet the
requirements [4][5] of vendor's u-boot-spl for u-boot, a binman node with
mkimage child node is added here, which will compress u-boot.bin with
gzip and generate an image named "uboot" in the file u-boot-gz.img.

Enable OF_UPSTREAM to use upstream DT and add starfive/ prefix to
the DEFAULT_DEVICE_TREE. Rename jh7110-starfive-visionfive-2-u-boot.dtsi
to jh7110-starfive-visionfive-2-v1.3b-u-boot.dtsi and set the v1.3b
device tree as the default device tree.
Drop redundant DT files from arch/riscv/dts/ and redundant clock and
reset definitions from include/dt-bindings/.
Since the old clock definitions is a little different from those in
upstream Linux, update the clock definitions in clock drivers
accordingly.

The U-Boot copy of the mpfs devicetree has, in general, been neglected
somewhat in comparison to the one in Linux. Moving to OF_UPSTREAM to
keep both in sync should serve to eliminate that discrepancy.
Additionally, moving to OF_UPSTREAM will let U-Boot automatically pick
up the devicetree rework that is in progress at [1].

When building for a custom board, it is quite common to maintain a
private branch which include some defconfig and .dts files. But to
hook up those .dts files requires modifying a file "belonging" to
upstream U-Boot, the arch/*/dts/Makefile. Forward-porting that branch
to a newer upstream then often results in a conflict which, while it
is trivial to resolve by hand, makes it harder to have a CI do "try to
build our board against latest upstream".
The .config usually includes information on precisely what .dtb(s) are
needed, so to avoid having to modify the Makefile, simply add the
files in (SPL_)OF_LIST to dtb-y.
A technicality is that (SPL_)OF_LIST is not always defined, so rework
the Kconfig symbols so that (SPL_)OF_LIST is always defined (when
(SPL_)OF_CONTROL), but only prompted for in the cases which used to be
their "depends on".
nios2 and microblaze already have something like this in their
dts/Makefile, and the rationale in commit 41f59f68539 is similar to
the above. So this simply generalizes existing practice. Followup
patches could remove the logic in those two makefiles, just as there's
potential for moving some common boilerplate from all the
arch/*/dts/Makefile files to the new scripts/Makefile.dts.

Sync the hifive-unleashed-a00 dts from Linux with

Idea is to periodically sync the dts from Linux instead of
tweaking internal changes one after another, so better not
add any intermediate changes in between. This would help to
maintain the dts files easy and meaningful since we are
reusing device tree files from Linux.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.
