ramips: fix dtc compiler warnings

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"
