ASoC: meson: aiu-encoder-i2s: fix bit clock polarity

Browse source

[ Upstream commit 4c4ed5e073 ]

According to I2S specs audio data is sampled on the rising edge of the
clock and it can change on the falling one. When operating in normal mode
this SoC behaves the opposite so a clock polarity inversion is required
in this case.

This was tested on an OdroidC2 (Amlogic S905 SoC) board.
