clk: imx8mp: Fix the parent clk of the audio_root_clk
Having the parent of the audio_root_clk set to ipg_root in the clk-imx8mp.c, there is a hang happening when the audiomix IP regs are accessed. Switch parent to audio_ahb. And we could also refer to the section "5.1.4 System Clocks" of the IMX8MPRM.pdf, the parent clk of CCGR101 (Audiomix) is the AUDIO_AHB_CLK_ROOT.
