The PCA9633 i2c LED controller offers an All Call address in its nominal
operation, allowing simultaneous communication with all instances present
on the same i2c bus. The default address is 0x70. While this functionality
is convenient, it is possible that the board uses another i2c component
that also uses this address (for example, the shtcx). In such cases, the
address conflict prevents the proper functioning of the system.
The idea is to add a "disable-allcall" property to the device tree. If this
option is present, the initialization of the PCA9633 forces the bit 0
(ALLCALL) to be set to false, thereby disabling this function. It is
necessary to add this property to all PCA9633 devices on the bus to free up
the address 0x70.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

PCA9633 driver does not cunnetly support multiple devices.
Updated the driver to use DT_INST_FOREACH_STATUS_OKAY to
configure all devices defined in the device tree.
Convert driver to use `i2c_dt_spec` helpers.

move misc/util.h to sys/util.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.
