In some cases, the sysclk won't be configured on init, and sysclk can be
changed in hw_params() according to different sample rate, for example,
for 44kHz sample rate, the sysclk is 11.2896MHz, for 48kHz sample rate,
the sysclk is 12.288MHz.
In order to support the above case, only enable constraints when sysclk
is configured, and check the rate in hw_params.
So overall there are three cases that need to be considered:
- call set_sysclk() on init, then constraints will be initialized.
- don't call set_sysclk() on init, but call it after startup(), then
constraints will be configured, the constraints can be cleared with
call set_sysclk() again in shutdown().
- don't call set_sysclk() in the whole flow, then there are no any
constraints. The clocks depend on cpu dai.
Enlarge the WM8524_NUM_RATES to 12, as the supported rate range is 8kHz
to 192kHz.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The ASoC core has now been changed to default to the non-legacy DAI
naming, as such drivers using the new scheme no longer need to specify
the non_legacy_dai_naming flag.

On an imx8mq-evk the following error is seen:
[ 1.375809] wm8524-codec audio-codec: Failed to get mute line: -517
It happens because the codec driver may probe prior to the imx gpio
driver, which causes a probe defer.
Change to dev_err_probe() to avoid printing this error.
