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.

There are several different issues when trying to build the icm42605
sensor driver:
* Missing entry in drivers/sensor/CMakeLists.txt
* Issues with #ifndef in header files
* Issues with const usage
* Missing function prototypes in headers
* Fix use of LOG_MODULE_REGISTER v LOG_MODULE_DECLARE
* Add missing dts node to tests/drivers/build_all/spi.dtsi
