[PATCH v2 1/4] ASoC: dt-bindings: fsl-esai: Remove 'fsl,*' from required list

[Frank Li <Frank.Li@xxxxxxx>]

fsl,fifo-depth have default value 64 in driver(sound/soc/fsl/fsl_esai.c).

fsl,esai-synchronous is flag(bool) type. It doesn't make sense to put flag
type into 'required'.

Fix warning:

arch/arm/boot/dts/nxp/imx/imx6q-sabreauto.dtb: esai@2024000: 'fsl,fifo-depth' is a required property
arch/arm/boot/dts/nxp/imx/imx6q-sabreauto.dtb: esai@2024000: 'fsl,esai-synchronous' is a required property
