ASoC: davinci-mcasp: Remove redundant num-serializer DT parameter
The serial-dir array gives this information so there is no need to have the num-serializer property in DT description. Just ignore the property in the driver the DTS files can be updated separately without regression. Update the documentation at the same time for davinci-mcasp Signed-off-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Jyri Sarha <jsarha@ti.com> Signed-off-by: Mark Brown <broonie@linaro.org>
