Add device nodes for the I2C and IIC Controllers on the Renesas R-Car
M3-W+ (r8a77961) SoC, including DMA properties linking them to the DMA
controllers.

v2:
  - No changes.

Test procedure (MAX9611 ADC, BR24T01 EEPROM):
  1. "grep . /sys/bus/iio/devices/iio:device[01]/in*",
  2. "hd /sys/devices/platform/soc/e60b0000.i2c/i2c-?/?-0050/eeprom".

FWIW, I notice changed i2c indexes in dmesg depending if I include the
i2c aliases visible in below commits:

fcb008a75702c9 ("arm64: dts: r8a7796: add I2C support")
32bc0c51be7c9d ("arm64: renesas: r8a7795: add I2C support")
