ASoC: fsl_sai: Allow setting the SAI MCLK direction
On mx6ul the General Purpose Register 1 (GPR1) contains the following
bits for configuring the direction of the SAI MCLKs:
SAI1_MCLK_DIR, SAI2_MCLK_DIR, SAI3_MCLK_DIR
Introduce the "fsl,sai-mclk-direction-output" optional property to allow
configuring the SAI_MCLK outputs.
Tested on a imx6ul-evk board.
