The return value of clk_imx_acm_detach_pm_domains() is never used.
Simplify the code and turn it into a void function.

If devm_clk_hw_register_mux_parent_data_table() fails, we branch to the
error handling path and imx_check_clk_hws() is never called.
Actually, imx_check_clk_hws() is a no-op because values in 'hws' are either
valid, either NULL.
Move the call to imx_check_clk_hws() in the error handling path, so that
an error is logged.

If an error occurs after a successful clk_imx_acm_attach_pm_domains() call,
it must be undone.
Add an explicit error handling path, re-order the code and add the missing
clk_imx_acm_detach_pm_domains() call.

If a devm_clk_hw_register_mux_parent_data_table() call fails, it is likely
that the probe should fail with an error code.
Set 'ret' before leaving the function.

If a dev_pm_domain_attach_by_id() call fails, previously allocated
resources need to be released.

The Audio Clock Mux (ACM) is a collection of control registers
and multiplexers that are used to route the audio source clocks
to the audio peripherals.
Each audio peripheral has its dedicated audio clock mux
(which differ based on usage) and control register.
