Cache operations that act on unaligned buffers (with respect to cache
line) or buffers that are not multiple of the cache line size are at
least dangerous with an high risk of data and memory corruption.
While we do not enforce a contract on the buffer characteristics between
users and APIs, we can at least add a note in the documentation
specifying an undefined behaviour when the passed buffer is unaligned or
wrongly sized.

This code is meant to run in the context of a exception.
Most architectures will fail the asertion made in z_impl_k_sem_take()

This commit ensures K_NO_WAIT is used when arch_is_in_isr() is true.

Since the mtl platform, the stereo bit has been removed from the

(mtl and above), the configuration blob still has this bit set, causing the

driver to only display a warning.

If the address was removed immediately after being added (e.g. because the
interface MAC address is changed on boot), it would remain in the DAD timer
list.
In one scenario, the DAD timeout would eventually fire, causing the
now-removed address to be modified, potentially causing issues that way.
In another scenario, if the interface was immediately brought back up
again with a different link-local address, this new address would reuse the
first address slot on the interface. Starting the DAD process for this new
address would lead to the same address slot being added to the DAD timer
list a second time, causing an infinite list and associated lockup during
iteration.
Always remove the address from the DAD timer list when it is removed from
the interface, not just when DAD fails.

Don't assume the connection handle will always be 0. This is currently the
case with the Zephyr link layer, but recently changed in the Softdevice
Controller.
Another problem is that apparently the spec allows the controller to just
blackhole data instead of returning `BT_HCI_ERR_UNKNOWN_CONN_ID` if the
host uses a wrong handle.
