 Required properties:
-- compatible: Compatible list, contains "fsl,vf610-sai" or "fsl,imx6sx-sai".
-- reg: Offset and length of the register set for the device.
-- clocks: Must contain an entry for each entry in clock-names.
-- clock-names : Must include the "bus" for register access and "mclk1" "mclk2"
-  "mclk3" for bit clock and frame clock providing.
-- dmas : Generic dma devicetree binding as described in
-  Documentation/devicetree/bindings/dma/dma.txt.
-- dma-names : Two dmas have to be defined, "tx" and "rx".
-- pinctrl-names: Must contain a "default" entry.
-- pinctrl-NNN: One property must exist for each entry in pinctrl-names.
-  See ../pinctrl/pinctrl-bindings.txt for details of the property values.
-- big-endian: Boolean property, required if all the FTM_PWM registers
-  are big-endian rather than little-endian.
-- lsb-first: Configures whether the LSB or the MSB is transmitted first for
-  the fifo data. If this property is absent, the MSB is transmitted first as
-  default, or the LSB is transmitted first.
-- fsl,sai-synchronous-rx: This is a boolean property. If present, indicating
-  that SAI will work in the synchronous mode (sync Tx with Rx) which means
-  both the transimitter and receiver will send and receive data by following
-  receiver's bit clocks and frame sync clocks.
-- fsl,sai-asynchronous: This is a boolean property. If present, indicating
-  that SAI will work in the asynchronous mode, which means both transimitter
-  and receiver will send and receive data by following their own bit clocks
-  and frame sync clocks separately.
