[PATCH 15/16] arm64: dts: renesas: Add initial DTSI for RZ/G2{L,LC} SoC's

[Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>]

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
r9a07g044l1.dtsi => Specific to RZ/G2L (R9A07G044L single cortex A55) SoC
r9a07g044l2.dtsi => Specific to RZ/G2L (R9A07G044L dual cortex A55) SoC
