[jagannadh.teki@gmail.com (Jagan Teki)]

From: Jagan Teki <jagan@amarulasolutions.com>

Add support for Sound card and related codec(via i2c1) nodes
on Engicam Is.IoT MX6UL variant module boards.

Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>
---
Changes for v4:
- Move i2c1 into imx6ul-isiot.dtsi
Changes for v3:
- Replace fsl,imx-audio-sgtl5000 and use simple-audio-card
Changes for v2:
- Use proper [label:] node-name[@unit-address] for codec
- Remove incorrect codec property 'wlf,shared-lrclk'
- Remove 'gpr' from sound card node
