This is a per-thread register that gets updated only when context
switching. No need to load and save it on every exception entry.

The minimum stack alignment is 16. Therefore, the stack space to store
a struct __esf object must be rounded up to the next 16-byte boundary.
It is not sufficient to do the rounding on the __z_arch_esf_t_SIZEOF
definition. When the stack is constructed in arch_new_thread() it is
also necessary to do the rounding there too.
Let's make the structure itself carry the alignment attribute instead to
make it work in all cases.
While at it, remove the unused _K_THREAD_NO_FLOAT_SIZEOF definition.

Complete revamp of the exception entry code, including syscall handling.
Proper syscall frame exception trigger. Many correctness fixes, hacks
removal, etc. etc.
I tried to make this into several commits, but this stuff is all
inter-related and a pain to split.

Same rationale as preceding commit. Let's create pseudo-instructions in
assembly scope to make the code more uniform and readable.
Furthermore the definition of COPY_ESF_FP() was wrong as the width of
floating point registers vary not according to CONFIG_64BIT but
CONFIG_CPU_HAS_FPU_DOUBLE_PRECISION. It is therefore wrong to use
lr/sr (previously RV_OP_LOADREG/RV_OP_STOREREG) and a regular temporary
register to transfer such content.
Note: There are far more efficient ways to copy FP context around but
such optimisations will come separately.

Those are prominent enough that having RV_OP_LOADREG and RV_OP_STOREREG
shouting at you all over the place is rather unpleasant and bad taste.
Let's create pseudo-instructions of our own with assembler macros
rather than preprocessor defines and only in assembly scope.
This makes the asm code way more uniform and readable.

The thread->base.user_options field is an uint8_t. Access it using lb.
A "copy" of it is made into __esf.fp_state. Make that field an uint8_t
too and access it with lb/sb.
_callee_saved.fcsr is an uint32_t. Access it with lw/sw.
Ditto for is_user_mode.

The header file radio_df_vendor_hal.h was conditionally copiled in.
There were a dependency on a CONFIG_BT_CTRL_DR. The dependency is
removed because radio_df_vendor_hal.h and radio_df.h hasn't got any
DF related type dependencies. What more it allows to use IS_ENABLED
for code that uses types and functions defined in radio_df.h.

The EVENTS_CTEPRESENT is available when radio peripheral has
direction finding support. The event is set if received
PDU has CTEInfo and there were collected IQ samples during
CTE reception.
The event should be cleared always when other events are cleared.
That guarantees that the event is not set when use of radio for
following activities.

The radio_df_cte_ready function returns state of EVENTS_CTEPRESENT.
The function may not be used in create_iq_report function, because
it is called after lll_isr_rx_status_reset. The lll_isr_rx_status-
_reset clears EVENTS_CTEPRESENT value.
The result of this calls chain is lack of IQ sample report no matter
if the PDU has CTEInfo and radio has collected IQ samples.
To fix the problem, state of EVENTS_CTEPRESENT has to be get when
e.g. rssi_ready is get.

As Extended Advertising primary PDUs do not use ticker
remainder value for fine scheduling of radio events, do not
use the remainder value for auxiliary PDUs. This fixes the
jitter in the aux_offset value that caused the auxiliary PDU
being observed to be late compared to the aux_offset value
filled in the primary PDUs.

Core Specification 5.3 clarified security requirements for GATT client
when handling incoming notifications and indications.
Vol 3: Part C: 10.3.2.2:
"...Since the configuration is persistent across a disconnection and
reconnection, the client shall check the security requirements against
the configuration upon a reconnection before processing any indications
or notifications from the server. Any notifications received before
the security requirements are met shall be ignored. Any indications
received before the security requirements are met shall be confirmed
and then discarded. ..."

Currently when a node has a 'zephyr,memory-region' compatible and a
'zephyr,memory-region' string property, a new memory region is created
in the linker script.
Having a memory region without a section to place variables in could be
not that useful. With this patch we extend the memory-region mechanism
to also create sections.
The user can then place variables in the sections as usual by using for
example the GCC attributes.

This is an attempt at formally distinguishing and supporting the case
described in 40795 where an architecture doesn't preserve/restore the
complete thread state upon entering/exiting interrupt exception state.
This is mainly about promoting the current behavior from the accepted
workaround to a formal API specification. This workaround is currently
used on ARM64 but RISC-V requires it too.

Extend the macro with checks for DT properties related to pin
assignments that are defined but would be ignored, depending on
whether PINCTRL is enabled or not, what presumably indicates
a resulting configuration different from what the user expects.
Add also a possibility to indicate that the pinctrl-1 property
should not be checked because the caller does not support the
sleep state.
Rename the macro so that its name better reflects its function.
Update accordingly all drivers that use it.

The LoRa and LoRaWAN documentation was not included anywhere, so the
Doxygen comments in drivers/lora.h and lorawan/lorawan.h were not
rendered. This commit adds a new section for LoRa and LoRaWAN to the
documentation.
People often confuse the difference between LoRa and LoRaWAN, so it
makes sense to combine both in the same doc section.
LoRa would otherwise not fit very well into any docs category, as it
is a driver, but not really a peripheral.
