Some components of AUDIOMIX (i.e: DSP, OCRAM_A) are clocked by
AUDIO_AXI_CLK_ROOT. Since the AUDIOMIX block control manages the clock
gates for those components, include their root clock in the list of clocks
consumed by the IP.

ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx8mp-clock.h
