Added board definitions for nucleo_f756zg. Features include gpio,
pinmux, uart (ST Zio, ST-Link and Arduino Uno v3 interfaces).
Added basic documentation and some soc definitions for the
stm32 f756XX soc.

The various linker scripts on arc would include autoconf.h in the arch
linker script but might have CONFIG_ symbols referenced in the soc
specific linker script. Move autoconf.h inclusion to top of the soc
specific linker script out of the arch specific one so we know
autoconf.h is seen before any CONFIG_ references.

The early boot watchdog init for kinetis was incorrectly disabling and
reenabling interrupts to preserve timing during the unlock sequence.
However, interrupts are already disabled before this routine executes
and the kernel is not yet ready to enable them when this routine exits.

Adds a second sram node to the k64 device tree to acknowledge that the
additional sram is present in hardware, but deliberately not used in
zephyr until an outstanding issue is solved. The upper and lower sram
nodes are contiguous in the memory map, however the Cortex-M4
architecture does not support misaligned accesses across the boundary
between the two nodes.

It is safe to assume that if X_GPIO_CONTROLLER is defined (hence
generated) X_GPIO_PIN should also be defined.
If this is not the case, this is an issue and letting the sample
build will reveal the issue.
Update the yaml filter to rely only on _GPIO_CONTROLLER #define's

In disco basic sample, same GPIO controller was used for LED0
and LED1, which is actually a particular case.
This change implements the general case, where LED0 an LED1 might
not have the same gpio controller.
Tested on nucleo_f429zi and frdm_k64f.

Add support for SoF events to the USB STM32 device driver. When
CONFIG_USB_DEVICE_SOF is enabled, enable the corresponding interrupt
and provide a non-weak callback function calling status_cb.

Commit e4c447aac3 ("usb: add SoF event") added support for calling the
status callback with the USB_DC_SOF value for each SoF when
CONFIG_USB_DEVICE_SOF is enabled. The CDC ACM driver saves the latest
received status and compares it USB_DC_CONFIGURED to decide if it can
send data to the host. This therefore doesn't work any more when the
status callback is called regulary with USB_DC_SOF.
Fix that by ignoring USB_DC_SOF when saving the latest received status.

This patch adds a flash driver for the STM32F7x series, inspired from

work on other SoCs of the family.

On SoC families using a Cortex-M7, it is possible to flush only specific
cache lines. Therefore pass the offset and len so that the flush can be
done with more granularity.

In general synchronisation between memory and the instruction cache
should be done explicitly, for example this is how it is done for RAM.
It is also done that way for flash writes in the current STM32 flash
driver.
However in case of flash erases, the current STM32 flash driver flushes
the i-cache. It probably doesn't make a big difference for the
Cortex-M3/M4 families as the cache is very small. That said it might
have bigger impact on families based on Cortex-M7 as it has between 4KB
and 16KB of i-cache, that will be added latter in this patch serie.
This patch therefore remove the i-cache flush in
flash_stm32_flush_caches.

This reduces the amount of #ifdef and keep all of them at the same
place. The empty function is then optimized-out by the compiler.
At the same time change the negative test by a positive one to simplify
adding new entries.

The timeout handling in the STM32 flash driver is currently a counter
in the busy check loop. This doesn't scale well across the whole STM32
family:
- The duration of the loop depends on the CPU speed, the activation of
caches.
- The duration of the longest flash operation (a sector erase as the
driver doesn't support mass erase) can varies a lot mostly depending
on the sector size, 2K on F0 and L4 families or 128K on the F4 family.
In addition the timeout can change depending if the writing thread is
prempted or not.
Fix that by defining a timeout in ms depending on the family, and using
k_uptime_get to get a precise measurement of the time.

Currently there is a mixed approach in prefixes from mbedTLS

We currently get a number of warnings like:
Warning (simple_bus_reg): /soc/otgfs_phy: missing or empty
reg/ranges property
This is due to the usb phy nodes not have a reg property since they
don't have an mmio address associated with them.
Move the phy nodes out of the SoC node so their lack of a reg property
will not cause a warning. This is similar to how Linux dts files
handle the phy nodes.
