From: Lad Prabhakar <prabhakar.mahadev-lad.rj at bp.renesas.com>
Move RZ/G2UL SoC specific parts to r9a07g043u.dtsi so that r9a07g043.dtsi
can be shared with RZ/Five (RISC-V SoC).
Below are the changes due to which SoC specific parts are moved to
r9a07g043u.dtsi:
- RZ/G2UL has Cortex-A55 (ARM64) whereas the RZ/Five has AX45MP (RISC-V)
- RZ/G2UL has GICv3 as interrupt controller whereas the RZ/Five has PLIC
- RZ/G2UL has WDT2 (channel 2) whereas this block is missing on RZ/Five
- RZ/G2UL has interrupts for SYSC block whereas interrupts are missing
for SYSC block on RZ/Five
