Subject: [PATCH 3/4] arm: dts: nxp: imx6sx: fix esai related warning when
 do dtb_check

Remove undocumented compatible string 'fsl,imx6sx-esai', which never used
in driver sound/soc/fsl/fsl_esai.c.

Remove unused clock-names 'mem'.  Driver never use clock name 'mem'.

Fix below warning:

arch/arm/boot/dts/nxp/imx/imx6sx-sdb.dtb: esai@...4000: compatible:0: 'fsl,imx6sx-esai' is not one of ['fsl,imx35-esai', 'fsl,imx6ull-esai', 'fsl,imx8qm-esai', 'fsl,vf610-esai']
	from schema $id: http://devicetree.org/schemas/sound/fsl,esai.yaml#
