The latest dtc compiler considers nodes named i2c or spi as the
respective bus:
/pinctrl/i2c: incorrect #address-cells for I2C bus
/pinctrl/spi: incorrect #address-cells for SPI bus
Rename the node to fix the false positives.
Fix the spi node unit address for the DWR-512-B and UBNT-ER-e50 to get
rid of the following warning:
SPI bus unit address format error, expected "n"
