Add initial DTSI for RZ/G2{L,LC} SoC's.
File structure:
r9a07g044.dtsi => RZ/G2L family SoC common parts
r9a07g044l.dtsi => Specific to RZ/G2L (R9A07G044L) SoC

Do we want to use
SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause)
for new DTS files?
This actually also applies to <dt-bindings/...> files.

Please add interrupt-names.

This looks like a weird name ;-)
In addition, it should be the consumer clock name, not the provider
clock name.

As I think this is shared by RZ/G2L and RZ/G2LC, it belongs to

I think (at least) the first CPU core should be in the base
r9a07g044.dtsi file.
Probably the second CPU core should be in the base file, too, and
removed by /delete-node/ in r9a07g044l1.dtsi?

As some of the IP blocks present on RZ/G2L aren't present in RZ/G2LC
the clocks for the IP will be missing hence this is added to SoC
specific dtsi.

r9a07g044l1.dtsi with CPU maks to 1.

This overwrites the main compatible value set by r9a07g044.dtsi before.
As per your bindings, you want both:
compatible = "renesas,r9a07g044l1", "renesas,r9a07g044".
