Refactors the remaining I2S drivers to use the shared driver class
initialization priority configuration, CONFIG_I2S_INIT_PRIORITY, to
allow configuring I2S drivers separately from other devices. This is
similar to other driver classes.
The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to be
consistent with other driver classes.

Shims for nrfx drivers should only connect the related IRQ handlers,
they should not enable the IRQs, as this could lead to a situation
where the interrupt handler is called before the driver had a chance
to properly initialize the peripheral and install the provided event
handler. nrfx drivers will enable the interrupts appropriately on
their own by calling the NRFX_IRQ_ENABLE macro which is implemented
in nrfx_glue.h as a call to irq_enable().
This commit fixes the above issue spotted in the following shims:
- dmic_nrfx_pdm
- clock_control_nrf
- i2s_nrfx

Invalidate the cache before the RX data block is passed to the DMA
engine and not after it is received. If the RX data block contains
dirty cache lines they can be flushed anytime, overwriting legitimate
data that have been prefilled by the DMA module.

Some drivers explicitely casted data/config from void * to the

- correct the names of buffers used by message queues so that it
is possible to have multiple instances of the driver (in case
such need appears in the future)
- make `stop` and `discard_rx` normal structure members, not bit
fields, as they are modified in the interrupt handler and that
could lead to overwriting of other bit fields located in the
same memory unit
- add a log message providing the actual frame clock (WS) frequency
(i.e. PCM rate) that the driver was able to configure (due to
hardware limitations, it is not always possible to achieve the
exact requested frequency and the driver selects the closest one
available, so make it more visible to users

Remove unnecessary condition that effectively limits the usability
of the I2S format to two channels mode only.
Although the description of the `i2s_config` structure contains
a remark that for the I2S format the specified number of channels
is ignored and always two are used, in fact only one other in-tree
driver (i2s_sam_ssc) applies such limitation.
The nRF I2S hardware has no problem with handling the I2S format
with audio data for only one channel, so there is no need for having
this limitation in the driver, and without such mode of operation of
the driver it is impossible to feed it with PCM data directly from
the PDM peripheral working in one channel mode.

Add a shim that allows using the nrfx I2S driver via the Zephyr API.
Add also missing devicetree nodes representing the I2S peripherals
in the nRF52 Series SoCs.
Extend the "nordic,nrf-i2s" binding with a new property that allows
specifying the clock source to be used by the I2S peripheral (so that
it is possible to use HFXO for better accurracy of the peripheral clock
or, in the nRF53 Series SoCs, to use the dedicated audio oscillator).

Use `dma_reload()` instead of `dma_config()` within DMA callbacks. This
significantly shortens time required to reconfigure DMA engine to
transmit / receive the next data block and allows to configure higher
I2S bus data rates.
The maximum I2S data rate supported by the driver is still lower than
that of underlying hardware. To fully support hardware capabilities the
I2S driver would have to use scatter-gather / linked-list DMA transfer.
This is currently not supported by the DMA driver.

Introduce a new enumeration value that allows setting configuration

Such possibility is especially important on hardware where the streams
can be only enabled/disabled (but not started/stopped) independently,

The memory block passed by the user to the i2s_write function is
tightly packed next to each other.
However for 8-bit word_size the I2S hardware expects the data
to be in 2bytes which does not match what is passed by the user.
This will be addressed in a separate PR once the zephyr API committee
finalizes on an I2S API for the user to probe hardware variations.

In the I2S CAVS driver, the DMA user data simply points to
the device struct. However, after the change to const-ify device
struct, this causes warnings from compiler because the user_data
assignment would discard the const qualifier. The user_data is
being used to point back to the device struct, and the DMA
callbacks are already casting the user data argument into
a const device struct. So it's a simple fix by casting
the device pointer to void pointer at device creation.
