This introduces yet another memory blocks allocator where:
() All memory blocks have a single fixed size.
() Multiple blocks can be allocated or freed at the same time.
() A group of blocks allocated together may not be contiguous.
This is useful for operations such as scatter-gather DMA
transfers.
() Bookkeeping of allocated blocks is done outside of
the associated buffer (unlike memory slab). This allows
the buffer to reside in memory regions where these can be
powered down to conserve energy.

This sentence ("Other hardware features are not supported by the
Zephyr kernel."), which could be found in a high number of boards
documentation, is misleading on two levels:
- peripheral support is not a kernel business
- in most of cases, features are actually supported but not enabled.
Fix this.

This has bitrotten a bit. Early implementations had a synchronous
arch_start_cpu(), but then we started allowing that to be an async
operation. But that means that CPU start now becomes surprisingly
reentrant to the arch layer (cpu 0 can get a call to start cpu 2 while
cpu 1's initialization code is still running). That's just error
prone; we never documented the requirements cleanly (the window is
very small, but not so small to a slow simulator!).
Add an extra flag so we don't issue the next start until the last is
out of the arch layer and running in smp_init_top().

This is trick (mapping RAM twice so you can use alternate Region
Protection Option addresses to control cacheability) is something any
Xtensa hardware designer might productively choose to do. And as it
works really well, we should encourage that by making this a generic
architecture feature for Zephyr.
Now everything works by setting two kconfig values at the soc level
defining the cached and uncached regions. As long as these are
correct, you can then use the new arch_xtensa_un/cached_ptr() APIs to
convert between them and a ARCH_XTENSA_SET_RPO_TLB() macro that
provides much smaller initialization code (in C!) than the HAL
assembly macros. The conversion routines have been generalized to
support conversion between any two regions.
Note that full KERNEL_COHERENCE still requires support from the
platform linker script, that can't be made generic given the way
Zephyr does linkage.

Subghzspi instances cannot have any pinctrl configs,
they are blacklisted by the dts binding. This caused an
initialization failure of the spi_ll_stm32 driver for
subghzspi instance because no "default" pinctrl was found.
This commit solves the problem by skipping the pinctrl setup
for subghzpi devices. The use_subghzpi_nss property is used
to identify a subghzspi device, as this is a required boolean
property only available in the subghzspi binding this is a
perfect indicator for such instances.

Default value for CONFIG_BT_CTLR_LLCP_PROC_CTX_BUF_NUM was set to

Many ARM SoCs included <devicetree.h> likely due to:
1. nvic.h not being self-contained
2. As a result of copy-paste
Some RISC-V SoCs had the same problem, in this case likely due to
copy-paste from ARM. The <devicetree.h> header has been removed using

Certain stm32 soc's have a single shared irq for all adc channels
on those soc's only a single channel is supported.
Added a Kconfig that enables a shared irq for stm32f2x, stm32f4x,
stm32f7x soc's. The shared IRQ uses a flag to limit the number of
interrupts defined to only 1. A shared irq handler is added which
determines which ADC instance the interrupt is for, it then calls
into the existing interrupt.

debugging). J-Link option has also been enabled as it seems to be more
