[PATCH v1 2/5] arm64: dts: qcom: shikra-iqs: Add LT9611UXD HDMI audio overlay

[Karthik S]

Add a device tree overlay for Shikra IQS EVK boards that use the
LT9611UXD HDMI bridge as an I2S audio codec instead of the MAX98091.

The overlay reconfigures the sound card compatible to
qcom,shikra-iqs-lt9611uxd-sndcard, overrides the primary I2S playback
codec to LT9611UXD, disables the capture DAI link, and disables the
MAX98091 codec node.

Add a node label to the sound node in shikra-iqs-evk.dts to allow the
overlay to reference it, and wire up the new composite DTB in the
Makefile.
