Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Move logging out of misc/ to its own subsystem. Anything related to
logging and any new logging features or backends could be added here
instead of the generic location in misc/ which is overcrowded with
options that are not related to eachother.

Such stack size might vary if debug is enabled or not and depending also
on other factors. Let's do the same for priority as well, putting it to
high prio as default (15 is way too low level).

ll_len means link layer length, but it's misleading here as ll_len is
the whole net buffer length: reserved ll length + payload length.

At this point, if the frame was accepted by the controller, it means
that CRC was valid. Thus, there is no reason to get it in the buffer.
Let's just pop it out from controller's memory.

The default kernel init priority is too low. Make this
configurable and set the default priority so that the
ethernet driver is started just before the network stack.
This commit adds generic ethernet priority and changes
currently available ethernet drivers to use it.

The original commit:

has changed because an internal rebase. Two lines adding an SPI
command are missing.
This commit adds back the missing lines.

The ENC28J60 hardware module does not support concurrent
transmission and reception.
This fix adds a control semaphore to exclude the execution
of both processes.
Applies the equivalent changes to the legacy driver.

Tranmission: Consider that fragments are no adjacent.
Reception: Consider receiving data in more than one fragment.
SPI routines: Align SPI fragment size with default buffer fragment
size (128 bytes) for better performance.

Everytime the devices receives a frame with odd length it will
add an extra byte of padding to the reception buffer.
This was causing and issue when receiving frames above 64 bytes
length and with odd length.
This commit pops the extra padding byte everytime the received
frame has an odd length.
The equivalent fix is applied to the legacy driver.

When the driver receives or transmits a frames with a length
that is multiple of MAX_BUFFER_LENGTH the last block would be
read/sent twice to spi because a missed calculation on
num_remaining.
The issue is fixed by controling when the remaining bytes are
written/read into the spi device and by setting the spi command
on each spi write/read attempt.
The fix is applied to the legacy driver as well.

PRIMARY, SECONDARY, NANOKERNEL, MICROKERNEL init levels are now
deprecated.
New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.
Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

The driver originally gets the full-duplex configuration
from the PHCON1 register and PDPXMD bit as stated by the
ENC298J60 specification document section 2.6 "LED Configuration".
This section trust the board to LEDB connection to signal the
full-duplex configuration.
This commit gets the full-duplex configuration from Kconfig
symbols to allow a proper functionality even when the board
is not connecting LEDB apropriately.

There is a tx semaphore that controls a single access to the
transmission service. The device is capable to manage a single
transmission call at a time. Multiple requests need to wait
for the resource to be free.
This commit adds the initial release to the tx semaphore.

SPI bus is a shared resource between tx and rx processes.
The access to it must be synchronized to allow a rx process to
happen even when a tx process is taking place.
ECON1 register must be saved by the rx process and recovered
at the end to ensure that the tx process will continue operating
in the same register bank.
