[PATCH v3 7/8] arm64: dts: qcom: shikra-iqs-evk: Enable sound card support

[Mohammad Rafi Shaik <mohammad.rafi.shaik@oss.qualcomm.com>]

Enable the IQS EVK audio card using MAX98091 on I2S0 for primary
playback/capture and VA DMIC capture through q6apm backend links.

Add board clock and pinctrl states required for codec IRQ, external
mclk and digital mic routing.
