arch/arm64/boot/dts/renesas/r8a779g3-sparrow-hawk.dtb: Warning (spi_bus_reg): Failed prerequisite 'spi_bus_bridge'
The Sparrow Hawk uses the MSIOF module in I2S mode instead of SPI mode,
triggering a conflict between the SPI bus bindings and dtc:
- Serial engines that can be SPI controllers must use "spi" as their
node names,
- Dtc assumes nodes named "spi" are always SPI controllers.
Fix this by disabling this specific warning for this board.
