MLK-24365-1 dts: dsp: manage audiomix clock in dsp driver.
IMX8MP_CLK_AUDIO_ROOT and IMX8MP_CLK_AUDIO_AXI_DIV will be gated when
suspend even if dsp driver ignored suspend when low power audio offload
playback. The root cause is the two clocks is controlled when audiomix
power on/off. Add the two clocks in dsp driver, so driver will add
one ref count when useing dsp, so the two clocks don't be gated when
A core suspend during low power audio playback.
