3609e1dc5f dts: automatically build necessary .dtb files
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 41f59f6853 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.

f70ca794be sh: r2dplus: Add SCIF1 to the basic DT
Add simple DT and clock bindings to r2dplus DT to permit U-Boot
to bind the SCIF driver via DT probing instead of hard-coded
config options.

a12c90a28d sh: r2dplus: Fix missing PCI range
Add missing PCI range for translating DRAM to bus addresses.
This fixes e.g. PCI NIC interface and allows network to work
in QEMU.

eaae4ee2bd sh: r2dplus: Switch to DM PCI driver
Add DT entry for the DM PCI driver, update board configs
and drop ad-hoc board init code for the PCI bus. Instead,
let the DM PCI driver initialize and operate the hardware.

8c2c46350d sh: r2dplus: Enable OF control
Enable OF control for SH4 R2Dplus board. This is necessary, because
the PCI uclass is designed in a way that makes it depend on DT and
disallows instanciating devices without DT (e.g. with platdata).
