Add support for Low Speed External 32.768 kHz oscillator (LSE ).
Add support for MSI PLL-Mode offering an automatic calibration feature
in combination with the LSE. This allows the MSI to reach an accurate
+/-0,25% clock perfectly suitable for USB full-speed clock.

Following the recent NVS changes, the following warning now appear with
GCC 7.3 when building with -O2:
ZEPHYROOT/subsys/fs/nvs/nvs.c: In function 'nvs_reinit':
ZEPHYROOT/subsys/fs/nvs/nvs.c:92:36: warning: 'addr' may be used
uninitialized in this function [-Wmaybe-uninitialized]
offset += fs->sector_size * (addr >> ADDR_SECT_SHIFT);
~~~~~~^~~~~~~~~~~~~~~~~~~
ZEPHYROOT/subsys/fs/nvs/nvs.c:606:8: note: 'addr' was declared here
u32_t addr;
^~~~
This was already reported by Coverity earlier as CID:187903.
In practice this can only happen if fs->sector_count equals 0, which is
not possible as checked in nvs_init(). At least in the GCC case, it
believes that k_mutex_lock(&fs->nvs_lock, K_FOREVER) could modify
fs->sector_count.
Workaround the issue by initializing addr to 0.

The current NVS code checks for an empty ATE using th
_nvs_flash_cmp_const() function. This function loads the data and
compare them to a value. This means that when executed multiple on the
same area, the data get reloaded multiple time. This might have a
noticeable performance impact with an SPI flash.
Instead define a function _nvs_ate_cmp_const to compare an already read
struct nvs_ate with a constant value. Then replace the calls to
_nvs_flash_cmp_const() on struct nvs_ate by _nvs_flash_ate_rd() followed
by _nvs_ate_cmp_const(). This also has the advantage of explicitly
checking for errors instead of testing the error and the result of the
comparison at the same time.
Tested on a Nucleo L432KC board with the nvs sample. The maximum
initialization time (ie just before running the first garbage collector)
goes down to 6213 µs from 7350 µs.

As this was written before, a 'FLAOT' menu entry was present, and to
see what kind of features or configuration it had, one had to navigate
into the menu to determine if anything related to 'FLOAT' was enabled
at all.
Now there is an unchecked box on the 'FLOAT' menu when it is disabled,
which clearly expresses that it is disabled without the need to enter
the menu entry.
This change only changes the menu layout, and not the dependencies of
any options.

Kconfig options are often either of the type 'feature' or
'configuration'. Meaning, either an option controls whether a feature
is enabled, or it adjusts/configures an already enabled feature.
Configuration of features should depend on the feature they are
configuring or else noise is created both in the Kconfig output and in
the Kconfig menu.
In this commit we add a dependency from a configuration option to it's
feature option.

The bulk of implementation in the current DFU arch is done in the ISR.
This works well when the Flash device is memory mapped as these writes
get done comparatively quickly. However, in case of platforms where
the flash device is sitting on the SPI Bus, this was observed to
cause an exception. This exception may be because there are multiple
function calls consuming larger processing time inside the ISR. The
ISR stack may also end up going deeper and risk stack corruption on
devices with low RAM. To resolve this, we deferred flash write to a
worker thread. Also, some handshaking was added to have synchronization
with the host in accordance with the Host-Device DFU protocol.

Features:
- Uses the SPI bus to communicate with the card
- Detects and safely rejects SDSC (<= 2 GiB) cards
- Uses the optional CRC support for data integrity
- Retries resumable errors like CRC failure or temporary IO failure
- Works well with ELMFAT
- When used on a device with a FIFO or DMA, achieves >= 310 KiB/s on a
4 MHz bus
Tested on a mix of SanDisk, Samsung, 4V, and ADATA cards from 4 GiB to

Note that the function itself is not checking for overflow yet since
I'm not sure this can happen and/or is a problem. Though now we have
only one single point to fix this problem.

In general driver system calls are implemented at a subsystem
layer. However, some drivers may have capabilities specific to
the hardware not covered by the subsystem API. Such drivers may
want to define their own system calls.
This macro makes it simple to validate in the driver-specific
system call handlers that not only does the untrusted device
pointer correspond to the expected subsystem, initialization
state, and caller permissions, but also that the device object
is an instance of a specific driver (and not just any driver in
that subsystem).
