This is a zero-copy networking implementation of Ethernet driver.
Limitations:
- one shot PHY setup, no support for PHY disconnect/reconnect
- no support for devices with DCache enabled due to missing
non-cacheable RAM regions in Zephyr.
Tested on Atmel SMART SAM E70 Xplained board

All sample applicatons in Zephyr, using the ENC28J60 driver, set
the ETH_ENC28J60_0_GPIO_PIN Kconfig variable to 19.
However, in the Kconfig.enc28j60 file this variable is set to 24.
That default value, 24, was used only during the first iterations
of this driver and never used again.
In this patch, we set the Kconfig variable to 19 and simplify
project configuration files by removing one line.

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.

The ethernet controller being a freescale one, let's use its OUI. Then
only 3 bytes are needed for generating the rest of the MAC address.
Also, generating the MAC address in the right order.

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.

This commit removes the legacy Contiki based uIP stack.
The new native IP stack must be used after this commit.
The commit also removes following things:
- legacy cc2520 driver
- legacy ethernet drivers
- legacy IP stack samples
and changes these things:
- disabled tests that only work for legacy IP stack
- select new IP stack by default
- enable random number generator by default as it is needed
by the new IP stack

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.

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.
