Commit fdb6eb0a1287 ("ASoC: dapm: Modify widget stream name according to
prefix") fixed the case where a DAPM route between a DAI widget and a
DAC/ADC/AIF widget with a matching stream name was not created when the
DAPM context was using a prefix.
Unfortunately the patch introduced a few issues on its own like leaking the
dynamically allocated stream name memory and also not checking whether the
allocation succeeded in the first place.
It is also incomplete in that it still does not handle the case where
stream name of the widget is a substring of the stream name of the DAI,
which is explicitly allowed and works fine if no DAPM prefix is used.
Revert the commit and take a slightly different approach to solving the
issue. Instead of comparing the widget's stream name to the name of the DAI
widget compare it to the stream name of the DAI widget. The stream name of
the DAI widget is identical to the name of the DAI widget except that it
wont have the DAPM prefix added. So this approach behaves identical
regardless to whether the DAPM context uses a prefix or not.
We don't have to worry about potentially matching with a widget with the
same stream name, but from a different DAPM context with a different
prefix, since the code already makes sure that both the DAI widget and the
matched widget are from the same DAPM context.

The name field of the widget template is only used inside
snd_soc_dapm_new_control_unlocked() which allocates a copy for the actual
widget. This means we need to free the name allocated for the template in
dapm_kcontrol_data_alloc() and not the name of the actual widget in
dapm_kcontrol_free(). Otherwise we get a double free on the widget name and
a memory leak on the template name.

The commit 02aa78abec6e ("ASoC: DAPM: Add APIs to create individual DAPM
controls.") added locking to the snd_soc_dapm_new_control function but
did not update the call to snd_soc_dapm_new_control in the auto-disable
mux code, this appears to be because the patches were sent at fairly
similar times.
This patch change the call in the auto-disable mux code to use the new
snd_soc_dapm_new_control_unlocked function instead.

Instead of hard wiring the WCLK frequency at probe time do it runtime.
The hard wired 88_96KHz was not even setting the correct bits since it was
defined as (1 << 6) which will change the I2S_OUT_SEL bit and will leave
the amplifier configured for 8KHz.
At the same time clean up and fix the CFG3 register bits.

Execute this sequence via DAPM_POST widget.
Remove patching the RESERVED_0D register at probe time since it has to be

In order to be able to execute the sequence at the correct time, the driver

The PDM clock can be selected via bit0-1.
PDM_DATA_ES bit is at bit2.
The code were trying to select BCLK as PDM reference clock but instead
it was selecting PLL and set the DATA_ES bit to 1.
Selecting the PLL output as reference clock as default does make sense,
but the driver should not change the PDM data edge.
