Currently there is no way to distinguish between a caller
explicitly asking for a semaphore with a limit that
happens to be `UINT_MAX` and a semaphore that just
has a limit "as large as possible".
Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin
to `K_FOREVER` versus just passing some very large wait time.
In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.
These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`
where appropriate.

Convert from device_get_binding to DEVICE_DT_GET. In doing this we
no longer need the label in the devicetree node so we remove that.
Removed all __ASSERT_NO_MSG(clk) since we'll get a build error if
DEVICE_DT_GET cant be satisfied, and the clock control api's will
handle reporting if the device_is_ready.

When setting the MAC address, the ethernet driver has to call
net_if_set_link_addr() with the updated address. This was missing and is

Modify the ethernet driver to use TX complete interrupts.
Adds HAL ethernet TX complete callback and locking semaphore.
Due to changing behavior/content of the TX DMA descriptors
on STM32H7 series, based on the state of the IP,
it is more reliable to wait for the TX complete interrupt to check
for DMA end of transmission event. This avoids polling the
DMA_DESC_OWN bit in the descriptors.
Improves reliability and performance of the ethernet peripheral.
Tested on CoapServer sample, Dumb HTTP server, telnet sample.

The check for assertion on the "config_func" was added to
validate that the function pointer is valid. However, in
the code we are invoking the "config_func" and comparing
its output with NULL. This causes build failures with

All initialization of the Ethernet interface is done in the
eth_initialize function which is invoked by the boot code.
This function sets up DMA, programs the Ethernet module and
enables IRQs. However, this function does not setup "netif"
interface info which is done when the ethernet device is
enumerated by the NET stack via the "iface_api.init" func.
However, after the eth_initialize func is called, it is
possible that the system receives RX interrupts, and the
"rx_thread" accesses the "netif" pointer to get iface info.
However, because the "netif" info is not necessarily
populated at this time, we get a crash (as OS does NULL
access).
Fixed by enabling Ethernet IRQ after the interface is
properly setup.
Tested on Nucleo F767Zi board.

Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

The driver-specific config_info structure referenced from the device
structure is marked const. Some drivers fail to preserve that
qualifier when casting the pointer to the driver-specific structure,
violating MISRA 11.8.
Changes produced by scripts/coccinelle/const_config_info.cocci.
Some changes proposed by the script are not included because they
reveal mutation of state through the const pointer, though the
code works as long as the driver-specific object is defined without
the const qualifier.
