ASoC: sun8i-codec: Fix left and right channels inversion

commit 18c1bf35c1c09bca05cf70bc984a4764e0b0372b upstream.

Since its introduction, the codec had an inversion of the left and right
channels. It turned out to be pretty simple as it appears that the codec
doesn't have the same polarity on the LRCK signal than the I2S block.

Fix this by inverting our bit value for the LRCK inversion.
