The commits adds support for nrf52840dk_nrf52840 with two additional
configurations:
- with FAT FS on internal SoC flash
- with FAT FS on QSPI connected MX25
In case of SoC configuration there is re-configuration of internal
partitions done, doe to need for at least of 64kiB for FAT FS.
The QSPI configuration only defines additional partition on
external device.

Provide a sample for ivshmem-doorbell running under virtualization
(QEMU). The sample relies on existing tools (ivshmem-server,
ivshmem-client) that must be run at the host (unix).
The sample can be run on userspace or kernelspace, and on arm64 (qemu,
kvm) and x86_64 (qemu) platforms.
This execution of this code is quite complex, thus the README should be
made available in the official documentation. This is why the code is a
sample and not a test.

The implementation of GIC v3 ITS uses k_aligned_malloc(), which will
only work if dynamic memory is available (system heap). Tell the user
that a dynamic memory pool is required.
The amount of memory will depend on registers probed during runtime.

The purpose of the GIC ITS is to translate message-passing interrupts into
LPIs. The LPI range starts at value 8192, which means the current default
value (200) is too low. Therefore, bump the highest IRQ number when ITS
is enabled.

The external flash chip is wired for QSPI. The chip, P25Q16H, has its
"Quad enable" bit in bit 9 of the Read Status Register (section 10.5 in
the datasheet), hence needs this particular quad enable requirement.

CFG register uses fields that are not defined in Synopsys databook of
Designware AHB DMA Controller.
Since current Zephyr code uses this driver only for the
intel_adsp_gpdma driver I assume that those fields are specific to
this DMA which is not the standard Designware one.
This patch allows to use either the standard Designware register or
the Intel one.

There are some issues with the current version of the code, mainly the
improper use of the internal OSC8M as a source for the DFLL48m without
division. The DFLL48M is designed to accept a maximum of ~33KHz
at it's input, as higher values will bring the multiplier down,
leading to instability.
Also added the following features:
* Support for external HF oscillator (XOSC)
* Support for crystal/external oscillators on XOSC32K/XOSC
* Automatic dividers/multiplier computation based on DT cpu frequency
* Support for user configurable NVM wait states
* Added option to skip clock (re)initialization (bootloader usecase).
Tests were performed on a custom SAMD20G18 board using different clock
sources and cpu frequencies.
Clocks were routed to GPIO pins and observed on a scope.
According to the datasheet, architecture is identical on D21/R21.
Due to the nature of the internal architecture and the fact that
DFLL48M is not really meant to output anything other than 48MHZ
some combinations of requested DT cpu frequency and source
frequency will not result in a perfect match.
Mostly insipred by the SAML21 implementation.

There is no need to use *_cmp_raw() functions here, all they do is cast the
pointers to in(6)_addr* and call the non-raw functions. Additionally, this
fixes a warning for the net_ipv6_addr_cmp_raw() call, which didn't cast the
arguments correctly.

This change adds a mutex to protect against simultaneous access to the bus
instead of returning an error during transfers. Since most I2C code doesn't
handle retries (especially with a -EIO code) not blocking on a mutex can
cause a number of problems.

This refactors the script to introduce a SectionKind enum that
represents each of the kinds of sections handled by this system (text,
data, rodata or bss), using that to improve the code structure by
reducing the use of strings in favor of indicating the use of values by
their types.

When using code_data_relocation the script identifies sections that
should be relocated, but cannot guarantee that section names are unique
across all linked files. If a section name is not unique then matching
all sections with that name across all input files will relocate more
data than intended.
As a simple example, if both file1 and file2 contain .rodata.strings
sections, then if gen_relocate_app inspects only file1 it will generate
a linker script fragment `*(.rodata.strings)` that matches both object
files.
This commit changes gen_relocate_app to make the linker match on object
files as well (`*file1.o(.rodata.strings)`) to ensure unwanted sections
don't get relocated.
