clk: imx93: Add IMX93_CLK_SPDIF_IPG clock
[ Upstream commit 6a7853544482e2336b5b8bb9a4b964f9d687f290 ]
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.
