Subject: ASoC: zx-i2s: flip I2S master/slave mode

From: Shawn Guo <shawn.guo@linaro.org>

commit a205c159f9e2db586a5ea475f4d22fa22e78fed8 upstream.

The SND_SOC_DAIFMT_MASTER bits are defined to specify the master/slave
mode for Codec, not I2S.  So the I2S master/slave mode should be flipped
according to SND_SOC_DAIFMT_MASTER bits.
