dt-bindings: net: dsa: nxp,sja1105: make spi-cpol optional for sja1110
Currently, the binding requires 'spi-cpha' for SJA1105 and 'spi-cpol'
for SJA1110.
However, the SJA1110 supports both SPI modes 0 and 2. Mode 2
(cpha=0, cpol=1) is used by the NXP LX2160 Bluebox 3.
On the SolidRun i.MX8DXL HummingBoard Telematics, mode 0 is stable,
while forcing mode 2 introduces CRC errors especially during bursts.
Drop the requirement on spi-cpol for SJA1110.
