At some point, the PDs from the Audiomix IP block will be added to the
drivers/soc/imx/imx8mp-blk-ctrl.c. Then, you'll have 2 drivers with the
same address range and the imx8mp-blk-ctrl also has runtime PM enabled.
My worry here is the possibility of imx8mp-blk-ctrl audiomix (when that
will be added) will mess with the PD leaving your clock provider driver
hanging.
