The APA102 is a RGB LED with integrated controller. LEDs can be
daisy-chained and use SPI for communication. The SPI port is
configured via Device Tree.
Tested on the Adafruit Trinket M0.

Prior to this commit, `flash_area_layout()` was being passed a pointer
to the incorrect type (`uint32_t *` where `int *` was expected). This
caused the following warning to be reported:
```
[...]/subsys/storage/flash_map/flash_map.c: In
function 'flash_area_get_sectors':
[...]/subsys/storage/flash_map/flash_map.c:191:32:

This commit changes the argument type to `u32_t` for both functions.

This fixes the issue when after incomplete timer expiration
host sent ACK.
The host failed in two cases:
1. Sending ACK right after the incomplete timer expiration;
2. Sending ACK from new RX context. Now, seq_auth of cancelled
message is not cleaned on RX reset, so segments of cancelled message
will be discarded when resend.
According to the Mesh Profile v1.0
"When the incomplete timer expires, the lower transport layer
shall consider that the message being received has failed and
cancel the acknowledgment timer. Any segment of a canceled
message shall be ignored."

Instead of composing expressions with a logical AND, break down it into
multiple assertions. Smaller assertions are easier to read. While at
it, compare pointers against the NULL value, and numbers against 0
instead of relying on implicit conversion to boolean-ish values.

Without the parenthesis, the code was asserting this expression:

Where it should be this instead:

When both PB-ADV and PB-GATT are enabled, the PB-ADV code (prov.c)

In net_app_init_client(), the remote port is set after an initial
set of checks based on the remote_addr's assigned family.
However, if the peer_addr_str is a host name which needs to be
resolved via DNS, the family won't be set yet, and the port is
left as 0.
To fix this behavior let's move the port assignment after the
DNS lookup section to be sure that the remote sa_family is set.

As discovered in https://github.com/zephyrproject-rtos/zephyr/issues/5952
...a duplicate call to k_delayed_work_submit_to_queue() on a work item
whose timeout had expired but which had not yet executed (i.e. it was
pending in the queue for the active work queue thread) would fail,
because the cancellation step wouldn't clear the PENDING bit, causing
the resubmission to see the object in an invalid state. Trivially
fixed by adding a bit clear.
It also turns out that the behavior of the code doesn't match the
docs, which state that a PENDING work item is not supposed to be
cancelled at all. Fix the docs to remove that.
And on yet further review, it turns out that there's no way to make a
test like the one in the linked bug threadsafe. The work queue does
no synchronization by design, so if the user code does no external
synchronization it might very well clobber the running handler. Added
a sentence to the docs to reflect this gotcha.
