ARM: dts: imx6qdl-wandboard: Fix audio channel swap

From: Fabio Estevam <[email protected]>

When running a stress playback/stop loop test on a mx6wandboard channel swaps can be noticed randomly.

Increasing the SGTL5000 LRCLK pad strength to its maximum value fixes the issue, so add the 'lrclk-strength' property to avoid the audio channel swaps.

Applied both, thanks.
