This patch refines the DT binding doc for more readability by adding
extra blank lines and indentations.

@ -5,32 +5,48 @@ which provides a synchronous audio interface that supports fullduplex
serial interfaces with frame synchronization such as I2S, AC97, TDM, and
codec/DSP interfaces.
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.
