generated_dts_board.h is pretty redundant and confusing as a name. Call
it devicetree.h instead.
dts.h would be another option, but DTS stands for "devicetree source"
and is the source code format, so it's a bit confusing too.
The replacement was done by grepping for 'generated_dts_board' and
'GENERATED_DTS_BOARD'.
Two build diagram and input-output SVG files were updated as well, along
with misc. documentation.
hal_ti, mcuboot, and ci-tools updates are included too, in the west.yml
update.

This commit adds driver support for DMA on f0/f1/f2/f3/f4/l0/l4
series stm32.
Notice due to some bugs, this is currently not working with f7.
There are two kinds of IP blocks are used across these stm32, one is the
one that has been used on F2/F4/F7 series, and the other one is the one
that has been used on F0/F1/F3/L0/L4 series.
Memory to memory transfer is only supported on the second DMA on
F2/F4 with 'st,mem2mem' to be declared in dts.
This driver depends on k_malloc to allocate memory for stream instances,
so CONFIG_HEAP_MEM_POOL_SIZE must be big enough to hold them.
Common parts of the driver are in dma_stm32.c and SoC related parts are
implemented in dma_stm32_v*.c.
This driver has been tested on multiple nucleo boards, including
NUCLEO_F091RC/F103RB/F207ZG/F302R8/F401RE/L073RZ/L476RG with the
loop_transfer and chan_blen_transfer test cases.

For LL header inclusion, use _STM32 Kconfig symbol
(related to the driver), rather than generic symbol,
that could theoretically use an alternate solution.

We shall not include core kernel headers in soc.h
header of ARM SoCs. We should try to only include
the vendor headers and auto-generated board header
from DTS. This commit implements this policy for
the SoCs, whose builds have shown to fail due to
header inclusion cycles.

This commit adds driver support for ADC1 on all 8 supported series of
stm32 with resolution and conversion time selection and calibration.
Currently DMA is not supported for all series, and without it, zephyr
won't be able to catch up ADC's end of conversion interrupt, so this
version of the driver supports one channel conversion only. Users want
multi-channel conversion should use multiple sequences in their app
code.
This driver uses LL lib rather than HAL because the current HAL lib for
ADC will call HAL_DMA_* functions rather than using zephyr's common DMA
interface, so that way the driver will break the consistency of the
code.
This driver has been tested on multiple nucleo boards including
NUCLEO_F091RC/F103RB/F207ZG/F302R8/F401RE/F746ZG/L073RZ/L476RG and all
passed the test cases in tests/drivers/adc/adc_api. If the external ADC
line is floating, it may fail the tests since ADC may get 0V and the
test cases think 0 is failing. Connect it to any voltage source between
0-3.3V will help passing the test cases.

exti driver implementation does not fit all SoCs because
some EXTI ip does not match stm32_exti register map provided.
Instead of providing exti register map for all SoCs, use LL API
which abstracts IP variations and enable uniform use of the drivers
on all STM32SoCs.

The original implementation of gpio functions access registers
directly. Using LL library can add a set of unifying access
functions for all series of stm32 for avoiding accessing low level
