[ Upstream commit 79935915300c5eb88a0e94fa9148a7505c14a02a ]
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.
