Calling cmake/pristine.cmake now requires SOURCE_DIR and BINARY_DIR as
arguments.
This ensures that pristine.cmake can evaluate if pristine is requested
on in-source builds, and bail out in such case with an error message.
All uses of `pristine.cmake` has been updated to use the new arguments.

This sample shows how to use the ADC API. Depending on the support of
sequential reads in the driver, 1 or 2 channels are read and printed.
A devicetree overlay is necessary to specify the used ADC channel(s).
Signed-off-by: Martin Jäger <martin@libre.solar>
The STM32 driver currently does not support reading a sequence of
multiple ADC channels. Only the first channel of the sequence was
read and the rest was silently ignored.
Fix: Return an error if reading multiple channels is requested.

When zefi.py was changed to pass compiler and objcopy the flag to
objcopy for the EFI target was dropped. This is because the current
SDK (0.12.1) doesn't support that target type for objcopy. However,
target is necessary for the images to be created correctly and boot.
Switch back to use the host objcopy as a stop gap fix, until the SDK
can support target for EFI.

Currently, if no net_pkt's are available, the radio driver RX thread
drops the 802.15.4 frame silently. This causes undesired behaviour,
where we can drop the packet which has already been acknowledged at
the 802.15.4 level.
Fix this, by blocking the RX thread if no net_pkt is avaliable. The
packets received while the RX thread is blocked will be accumulated in
the underlying nRF 802.15.4 driver, and eventually when it runs out of
internal buffers before the thread is unblocked, it'll stop
acknowledging the incoming frames.

The flash shell can now build when there isn't a chosen

The flash shell can work with any flash driver instance, not just the
one chosen by zephyr,flash-controller. It's helpful for the flash shell
to use this instance by default, but not required. We can switch
instances at runtime with the "flash set_device" command.
Fix the flash shell so it can build when there isn't a chosen
zephyr,flash-controller available.

Enables the FlexSPI NOR flash driver, configures the FlexSPI pins, and
updates the board documentation accordingly on the mimxrt1064_evk.
Note that this SoC has two FlexSPI instances: one instance has an
in-package QSPI flash used for XIP; the other instance has a board-level
QSPI flash used for storage, not XIP. This patch enables the flash
driver on the non-XIP flash only.
Tested with:

Introduces a new flash driver for the FlexSPI peripheral on i.MX RT
SoCs. The hardware provides a flexible sequence engine (LUT) that
supports various types of external devices, including serial NOR flash,
serial NAND flash, HyperBus (HyperFlash/HyperRAM), and FPGAs. It
supports up to four connected devices in single/dual/quad/octal modes
and provides memory-mapped read/write access to these devices through
the AHB bus.
The driver implementation consists of a shared controller for each
FlexSPI peripheral instance, and protocol-specific device drivers for
each external device. The controller provides a private interface for
multiple devices to access the FlexSPI peripheral registers. FlexSPI
devices provide the public flash driver interface to applications or
subsystems like storage or flash file systems; they also provide
protocol-specific LUT sequences to the controller.
Currently the only device type supported is QSPI NOR flash, but other
types like HyperFlash will be added later.
XIP is not yet supported, as this requires additional work to relocate
code to RAM and managing interrupts.

The strategy used in z_heap_aligned_alloc() was to allocate an extra
align-sized memory block for storing a pointer to the memory heap.
This is wasteful in terms of memory usage when alignment is larger
than a pointer width. A loop is needed to find the initial memory
start when freeing it which isn't optimal either.
Instead, let's have sys_heap_aligned_alloc() rewind a pointer after
it is aligned to make just enough room for storing our heap reference.
This way the heap reference is always located immediately before the
aligned memory and any unused memory is returned to the heap.
The rewind and alignment values may coincide in which case only
the alignment is necessary anyway.
