Geert Uytterhoeven 83596fbeb5 spi: core: Ignore unsupported Dual/Quad Transfer Mode bits ...

The availability of SPI Dual or Quad Transfer Mode as indicated by the
"spi-tx-bus-width" and "spi-rx-bus-width" properties in the device tree is
a hardware property of the SPI master, SPI slave, and board wiring.  Hence
the SPI core should not reject an SPI slave because an SPI master driver
doesn't (yet) support Dual or Quad Transfer Mode.

Change the lack of Dual or Quad Transfer Mode support in the SPI master
driver from an error condition to a warning condition, and ignore the
unsupported mode bits, falling back to Single Transfer Mode, to avoid
breakages when running old kernels with new device trees.

Fixes: f477b7fb13df (spi: DUAL and QUAD support)
