spi: core: Ignore unsupported spi-[tr]x-bus-width property values
Rejecting unsupported values of spi-tx-bus-width and spi-rx-bus-width may break compatibility with future DTs. Just ignore them, falling back to Single SPI Transfers. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Mark Brown <broonie@linaro.org>
