[PATCH 1/5] ASoC: cirrus: i2s: Fix LRCLK configuration

[Alexander Sverdlin <alexander.sverdlin@gmail.com>]

The bit responsible for LRCLK polarity is i2s_tlrs (0), not i2s_trel (2)
(refer to "EP93xx User's Guide").

Previously card drivers which specified SND_SOC_DAIFMT_NB_IF actually got
SND_SOC_DAIFMT_NB_NF, an adaptation is necessary to retain the old
behavior.
