Add device nodes for the I2C Bus Interfaces on the Renesas R-Car S4-8
(R8A779F0) SoC.
Based on a larger patch in the BSP by LUU HOAI.
Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>

R-Car S4 Series Hardware User's Manual Rev. 0.51 states I2C2 TX DMARS is
0x05, which is probably a typo?
Changed compared to the BSP:
- Replace GIC_SPI in reg property by 0,
- Add DMA-related properties.
