We can Run/Stall the DSP via audio block control bits found in audiomix.
Implement this functionality using the reset controller and use assert
for Stall and deassert for Run.

For EARC and EARC PHY the reset happens when clearing the reset bits.
Refactor assert/deassert function in order to take into account the
active_low configuration option.

Current code supports EARC PHY Software Reset and EARC Software Reset
but it is not easily extensible to more reset bits.
So, refactor the code in order to easily allow more reset bits in the
future.

This adds IMX8MP_AUDIOMIX_ prefix to internal macros in order to show
that specific macros are related to audiomix.

Add support for the resets on i.MX8MP Audio Block Control module,
which includes the EARC PHY software reset and EARC controller
software reset. The reset controller is created using the auxiliary
device framework and set up in the clock driver.
