When we build with newlib we don't set -nostdinc. In that case make
sure that we leave it to the toolchain to set the system include paths.
The one exception to leaving to the toolchain to set the system include
paths is the path to the newlib headers. Since we build
with -ffreestanding we need to make sure the newlib header path is the
before the toolchain headers. Otherwise the toolchain's 'freestanding'
headers get picked up and that causes issues (for example getting PRI*64
defined properly from inttypes.h due to __STDC_HOSTED__ being '0').
For newlib we accomplish this by having the only system header specified
by zephyr_system_include_directories() being just the newlib headers.
Note: for minlibc we leave things alone as things just happen to work as
the -I include of the libc headers takes precedence over -isystem so we
get the libc headers over the toolchain ones. For the newlib case it
appears that setting both -I and -isystem for the same dir causes the
-I to be ignored.

Removing the TX timeout handling in the GMAC driver (commit 18b07e09e0)
revealed some issues with the way hardware priority queues work.
For cases with both hardware priority queues enabled, with the default
recommended delta bandwidths (0% - 75%), the lower priority queue (0%)
is hardly able to send any packets. This became visible, because without
the timeout mechanism, we quickly ran out of available TX buffers if
there were multiple packets being queued to the queue.
Here is an excerpt from 802.1Q, chapter 34.3.1 which describes how Qav
bandwidth sharing SHOULD work:
The deltaBandwidth(N) for a given N, plus the deltaBandwidth(N) values
for any higher priority queues (larger values of N) defines the total
percentage of the Port’s bandwidth that can be reserved for that queue
and all higher priority queues. For the highest priority queue, this
means that the maximum value of operIdleSlope(N) is deltaBandwidth(N)%
of portTransmitRate. However, if operIdleSlope(N) is actually less
than this maximum value, any lower priority queue that supports the
credit-based shaper algorithm can make use of the reservable bandwidth
that is unused by the higher priority queue. So, for queue N-1, the
maximum value of (operIdleSlope(N) + operIdleSlope(N-1)) is
(deltaBandwidth(N) + deltaBandwidth(N1))% of portTransmitRate.
However in reality, the lower priority queues (N-1) on the SAM GMAC
hardware DO NOT use the bandwidth available from the higher priority
queues (N).
This commits fixes the issue by changing the defaults. These are still
set to the recommended 75% (total), but this percentage is split between
the priority queues manually.

Throughout the manual, the queues GMAC is equipped with are identified
by a number - Queue 0, Queue 1 and Queue 2.
However in the context of Qav, the queues are identified with a
character (note that there are only two queues as Qav is not used for
the non-priority queue) - Queue A and Queue B.
Queue B and Queue 2 are also called "the highest priority queues".
Based on that, the previous implementation was using the following
mapping:
Queue 1 - Queue A
Queue 2 - Queue B
However when running some specific tests, that is for example forcing
all the traffic to Queue 1, it showed that this queue is actually
affected by the Queue B registers. Similarly, Queue 2 seems to be
affected by the Queue A registers.
Based on that observation, this commit changes the registers used to
work with the following mapping:
Queue 1 - Queue B
Queue 2 - Queue A
Note that this is based solely on observations, there is nothing in the
datasheet that confirms this, and the "highest priority" label suggests
it is otherwise.

This option is meant to be used only for debugging. Use it to force all
traffic to be routed through a specific hardware queue. With this option
enabled it is easier to verify whether the chosen hardware queue
actually works.
This works only if there are four or fewer RX traffic classes enabled as
the SAM GMAC hardware supports screening up to four traffic classes.

The ARM Cortex-M 321 application note is stressing that
when enabling interrupts by executing CPSIE i(f), or by MSR

there is a need for synchronization barrier instructions,
if there is a requirement for the effect of enabling
interrupts to be recongnized immediately. _arch_irq_unlock()
is invoked in several places, therefore, we add the
barriers to make the interrupt enabling function
