between these root clocks.

Some of the features of the hdmi_ctrl will be used by some
different drivers in a way those drivers will know best, so adding the
syscon compatible we allow those to do just that. Only the resets
and the clocks are registered bit the clk-blk-ctrl driver.

In the reference manual the actual name is Audio BLK_CTRL.
Lets make it more obvious here by renaming from audiomix to audio_blk_ctrl.

that does
not fit into clocks or resets. Since the clocks are registered using the i.MX
clock subsystem API, the driver is placed into the clock subsystem, but it
also registers the resets. For the other functionalities that other GPRs might
have, the syscon is used.
