Flavio Ceolin 981ea3042e drivers: crypto: Keep namespace consistent
The API to set a callback has the namespace cipher but the driver
function pointer was using the namespace crypto. As this API belongs
to the cipher subgroup, just rename the function pointer in the driver
to be consistent.

Flavio Ceolin d1628ba035 drivers: crypto: Add cipher namespace in some API
Add 'cipher' namespace in some in the driver API since these
operations are for cipher.

Set a namespace to make it clear that these are cipher operations,
this allow further functionalities, like hash, to be added in this
driver API.

James Harris b10428163a kernel: sem: add K_SEM_MAX_LIMIT
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.

Xavier Chapron 824f423e54 misc: Replace assert include and calls by sys/__assert.h equivalent
Replace all calls to the assert macro that comes from libc by calls to
__ASSERT_NO_MSG(). This is usefull as the former might be different
depending on the libc used and the later can be customized to reduce

Kumar Gala 0bfd810d13 i2c: deprecate use of union dev_config
There are several issues with the dev_config union used as a
convenience when calling the i2c_configure api.  One, the union is well
name spaced protected and doesn't convey use with just i2c.  Second
there are assumptions of how the bits might get packed by the union
which can't be guaranteed.  Since the API takes a u32_t lets change in
tree uses to using the macros to setup a u32_t and make the union as
deprecated.
