The current mechanism of the MPU region switching configures and
reprograms the regions (including inserting, splitting the dynamic
region, and flushing the regions to the registers) every time during the
context switch. This, not only causes a large usage of the kernel stack
but also a lower performance.
To improve it, move the configuration operations ahead to make sure the
context swtich only flushes the current thread regions to the registers
and does not configure the regions anymore. To achieve this, configure
the regions during any operations related to partitions (partition
add/remove, and domain add/remove thread), flush the sys_dyn_regions if
the current thread is the privileged thread, and flush the thread's own
regions if it's a user thread.

Since bb590b5b6e, which enforces a more consistent ordering of
initialisation for devices, the ECIA initialisation was happening after
GPIO initialisation. This caused interrupts to stop working on GPIO
input.
This patch fixes that by increasing the default GPIO initialisation
priority, so that it happens after ECIA.

openamp shared memory regions can be anywhere in DDR memory
withing 2G range. Current SRAM_PRIV region is 64M which
prevents access of shared memory (vrings) by RPU (cortex-r5)
if it is out of 64M range. This patch allows vrings to be in DDR within
2G address space.

Enable SOC fixed MPU regions by default for the RT10xx/RT11xx SOC lines.
Additionally, add code to handle defining the SDRAM0 region as
device type (non cacheable, non shareable). This behavior can
be disabled with CONFIG_NXP_IMX_EXTERNAL_SDRAM=y. Set this Kconfig
for all boards in tree using SDRAM.
This will resolve an issue present on the RT11xx series where
the core may execute speculative prefetches to the SDRAM region when
no SDRAM is present on the board, resulting in the system faulting.

So far the init priories were:
enetc_psi0=60 < enetc_vsin=61 < emdio=70 < ethernet-phy=80
because the Ethernet PSI driver was doing global initialization for the
whole NETC complex, including enabling MDIO function (due to the way
the HAL works).
Change to use the default init priorities:
mdio=60 < phy=70 < eth=enetc_psi0=80 < enetc_vsin=81
by executing at an early stage the NETC global initialization. This also
allows to match the DT hierarchy representation of NETC with the
effective priorities assigned.

The sam0 CMCC configure Cortex-M cache controller. However, it is not
clear how the cache management should be performed. It is nor clear if
instructions like SCB_EnableICache can be used. In this case, if cache
management should be made only by CMCC it may require a dedicated
implementation.
Besides above, the CPU_CORTEX_M4 do not define cache by default which
can signal a bad configuration in tree since the SOC_SERIES_SAME54 do
not define which caches should be available.
This force cache controller disable to avoid issues.
