[PATCH v4 13/15] arm64: dts: freescale: imx93-phyboard-segin: Add I2S audio

[Primoz Fiser <primoz.fiser@norik.com>]

Add support for I2S audio found on phyBOARD-Segin-i.MX93. Audio codec
TLV320AIC3007 is connected to SAI1 interface as a DAI master. MCLK is
provided from the SAI's internal audio PLL (19.2 MHz).
