Subject: [PATCH v3 2/3] clk: imx93: Add IMX93_CLK_SPDIF_IPG clock

Split IMX93_CLK_SPDIF_IPG from IMX93_CLK_SPDIF_GATE
because the IMX93_CLK_SPDIF_GATE controls the gate
of IPG clock and root clock. Without this change,
disabling IMX93_CLK_SPDIF_GATE would also disable
the IPG clock, causing register access failures.

Fixes: 1c4a4f7362fd ("arm64: dts: imx93: Add audio device nodes")
