dt-bindings: net: dsa: nxp,sja1105: Add reset-gpios property 



Both the nxp,sja1105 and the nxp,sja1110 series feature an active-low
reset pin, rendering reset-gpios a valid property for all of the
nxp,sja1105 family.

  reset-gpios:

    description:

      A GPIO connected to the active-low RST_N pin of the SJA1105. Note that

      reset of this chip is performed via SPI and the RST_N pin must be wired

      to satisfy the power-up sequence documented in "SJA1105PQRS Application

      Hints" (AH1704) sec. 2.4.4. Connecting the SJA1105 RST_N pin to a GPIO is

      therefore discouraged.
