NVS lookup cache currently uses CRC8/16 as a hash function
to determine the cache position, which is not ideal choice.
For example, when NVS lookup cache size is 512 and 256
subsequent NVS IDs are written (that is, 0, 1.., 255), this
results in 128 cache collisions.
It is better to use a dedicated integer hash function. This
PR uses one of the 16-bit integer hash functions discovered
with https://github.com/skeeto/hash-prospector project. The
hash function was additionally tested in the context of NVS
lookup cache using simple NVS ID allocation patterns as well
as using real device NVS dump.
Also, add a test case to verify that the hash function is
not extremely bad.

The commit switches flash area access from FLASH_AREA_ macros
to FIXED_PARTITION_ macros and to usage of DTS node labels,
to identify partitions, instead of label property.

It is frequent to find variable definitions like this:
```c
static const struct device *dev = DEVICE_DT_GET(...)
```
That is, module level variables that are statically initialized with a
device reference. Such value is, in most cases, never changed meaning
the variable can also be declared as const (immutable). This patch
constifies all such cases.

The NVS data lookup time grows linearly with the number of
allocation table entries to walk through, meaning that if
some data pair in the NVS changes frequently, access to
other data pairs that change rarely can take a lot of time.
It is particularly visible when the NVS is used as the
settings backend since the backend needs to perform multiple
NVS reads to find a requested key.
Implement a simple cache that stores an address of the most
recent ATE for all NVS IDs that fall into the given cache
position. CRC8/16 is used as a hash function used to
distribute NVS IDs across the cache entries.
The cache entries are only invalidated when an NVS sector
is erased as part of the garbage collector task.

Replace DT_FLASH_DEV_NAME with DT_CHOSEN_ZEPHYR_FLASH_CONTROLLER_LABEL.
We now set zephyr,flash-controller in the chosen node of the device
tree to the flash controller device.
NOTE: For a SoCs with on die flash, this points to the controller and
not the 'soc-nv-flash' node. Typically the controller is the
parent of the 'soc-nv-flash' node).
