Subject: MLK-12745-3: ARM: dts: add sound card support for imx6ull-ddr3-arm2
 board

Add mqs, spdif and wm8958 sound card support in imx6ull-ddr3-arm2-wm8958.dts.
which can use the imx6ul-14x14-ddr3-arm2 socket board.
Add cs42888 sound card support in imx6ull-ddr3-arm2-cs42888.dts. ESAI use the
CSI PAD which conflict with the ov5640, so disable it.
