This adds multi-processing support for Intel Apollo Lake ADSP.
Some of the start-up code is borrowed from ESP32.

The DSP wall clock timer is a timer driven directly by
external oscillator and is external to the CPU core(s).
It provides a common and synchronized counter for all
CPU cores (which is useful for SMP), instead of
indepedently running local core timer (xtensa_timer).

The shared irq support isn't needed in this driver. We just need to
deal with the fact that some SoCs have only a single interrupt line and
some have three interrupts. We can just ifdef that based on
DT_NUM_IRQS.

Zephyr shields are mostly defined using references to the arduino
headers. There are featherwing shields like the Adafruit SSD1306
128x32 display that could work on feather form-factor devices if the
arduino I2C label was available. Add that label.

This is joint work with Kumar Gala (see signed-off-by).
Document the changes to the generated node macros in macros.bnf,
moving the old file to legacy-macros.bnf and putting it in its own
section.
The actual generated macros are now a low-level detail, so rewrite the
foregoing sections as examples in terms of the new <devicetree.h> APIs.

This commit reworks the Xilinx TTC timer driver to use the "match" mode
instead of the "interval" mode which counts up to the specified value
and resets to zero.
Using the "match" mode ensures that the timer keeps counting even after
an interrupt is triggered, and facilitates the tickless mode support
implementation.
This also allows `z_timer_cycle_get_32` to return the correct cycle
count when interrupt is locked; thereby, fixing the k_busy_wait hang
issue.
Note that the TTC "match" mode emulation (and tickless timer operation)
is only stable when the QEMU icount mode is enabled.

This commit enables the QEMU icount emulation mode for improved timing
stability.
In normal emulation mode (without icount), the emulation timing of the
TTC system timer is particularly unstable and this results in a high CI
failure rate.
For more details, refer to the issues #14173 and #22904.

Convert usb_stm32 driver to use of DT_INST macros.
Since driver is compatible with 3 different dt compatibles and
compatible string is included in DT_INST macros, I've kept the
DT_USB_ compatible agnostic macros based on DT_INST ones, which
allowed to remove fixup definitions.
Use of DT_USB symbols is now limited to usb_dc_stm32.
Additionally, compatible "st,stm32-otgfs" is removed from list
of compatibles for usbotg_hs ips.
