Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

This adds a new testcase in the spi_loopback test application
to use several buffers for the DMA transfer.
It requires the MOSI to be connected to the MISO of the SPI1.

This changes the spi_loopback test application to use the DMA transfer.
In case of DMA, some testcases are useless.
It requires the MOSI to be connected to the MISO of the SPI1.

move misc/printk.h to sys/printk.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

The return of memset is never checked. This patch explicitly ignore
the return to avoid MISRA-C violations.
The only directory excluded directory was ext/* since it contains
only imported code.

The frdm_kw41z runs at a much slower clock frequency than the frdm_k64f.
Increase the k_poll timeout in the asynchronous callback thread to allow
the spi transaction to complete on frdm_kw41z.

The testcase was using only SYS_LOG_ERR() to signal error conditions,
which would print useful error information to the console, but allow the
test to pass when it should fail. Add zasserts after every SYS_LOG_ERR()
to make the test fail properly.

The asynchronous callback thread was overflowing its stack and causing a
bus/mpu fault when hardware stack checking is enabled. Increase the size

tx_bufs/tx_count and rx_bufs/rx_count can be hold in another dedicated
structure, thus reducing the number of parameters to transceive. This
permits to avoid using the stack when calling transceive.
Since we saved parameters, we can expose back the struct device pointer,
to stay consistent with other device driver APIs.

Upcoming memory protection features will be placing some additional
constraints on kernel objects:
- They need to reside in memory owned by the kernel and not the
application
- Certain kernel object validation schemes will require some run-time
initialization of all kernel objects before they can be used.
Per Ben these initializer macros were never intended to be public. It is
not forbidden to use them, but doing so requires care: the memory being
initialized must reside in kernel space, and extra runtime
initialization steps may need to be peformed before they are fully
usable as kernel objects. In particular, kernel subsystems or drivers
whose objects are already in kernel memory may still need to use these
macros if they define kernel objects as members of a larger data
structure.
It is intended that application developers instead use the
K_<object>_DEFINE macros, which will automatically put the object in the
right memory and add them to a section which can be iterated over at
boot to complete initiailization.
There was no K_WORK_DEFINE() macro for creating struct k_work objects,
this is now added.
k_poll_event and k_poll_signal are intended to be instatiated from
application memory and have not been changed.
