When configuring an LPSPI module for a new device with different baud rate,
the module needs to be disabled for the baud rate change to take effect.
This adds the necessary call to LPSPI_Enable before initializing the
module.

For larger transfers DMA can be used enabling other tasks
to continue running. A threshold of 32 byte transfers
is about right and is defined threshold value for using DMA.
This does not currently support multiple SPI transactions changing
chip select with DMA (though the hardware supports this) currently.
Instead opting for the simpler first change of enabling one shot
DMA SPI transfers for those where the size warrants it.
Adds the loopback binding option to enable the spi_loopback test.

If the thread that submits data over spi is interrupted by a higher
priority thread while pushing data to the tx fifo the hardware pushes
data to spi and frees up space in the fifo. In this case more than
8 Bytes are written to the tx fifo and bytes in the rx fifo get lost
before they are collected in the rx while loop.
To avoid this, the tx loop is exited after a maximum of 8 bytes and the
rx loop will run until it collected all bytes from the rx fifo.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

The exist spi_transcieve_async API remains and uses the new
