Adds support for a devicetree property that controls the ClockDiv
value provided to the SDIO during init.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

Namespace in this context, will be a disk. It's not exposed from DTS, as
an actualy NVMe hardware controller card can bring more than one
namespace (disk).
Thus namespace are not instanciated through the device driver model, but
statically allocated and runtime configured, depending on what the
controller exposes.
By default the amount of namespace supported is one as it is the most
common setup.

This is the corner stone of the whole NVMe logic: sending commands and
getting replies, all through memory shared from the host to the
controller.
Then using it to inialize admit/IO queues and identifying the
controller.

Since Zephyr does not propose any advanced interfaces as FreeBSD (bus
abstractions, memory and DMA abstraction and many more), this comes with
a much simplified and Zephyr-ish way to instanciate, initialize and use
NVMe controller.
ToDo: IO Queues cannot be more than 1. Macros will need to be improved to
manage the case of 2+ IO queues.

Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".
Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.

MMC was using SDMMC kconfigs to build disk driver.
This is incorrect, MMC and SDMMC should not be sharing
Kconfigs. Split the drivers/disk/Kconfig.sdmmc into
drivers/disk/Kconfig.mmc and drivers/disk/Kconfig.sdmmc.
Also update disk tests to account for new MMC Kconfigs.

The HSI48 is enabled by clock control driver.
It is no more done by each driver that requires this clock
However when using rng or sdmmc or bluetooth/ipm or usb,
the HSI48 clock must be present in the DTS.
Add a warning for this particular check but keep the deprecated
HSI48 clock enable : keeping for legacy but to remove later.

Fail with error if any of flashdisk partition assumptions are not met:
* uniform page size through the whole partition
* flashdisk starts at page boundary
* flashdisk ends at page boundary
Read-only flashdisks are not subject to above conditions because the
cache buffer is not used for read-only flashdisks.
The checks can be disabled via Kconfig option to save code space.

Force cache-size to 0 and treat flashdisk as read-only when backing
partition has read-only flag set. This allows users to save RAM when the
application does not write to the flashdisk, e.g. when a predefined FAT
filesystem is used.

Cache written data to avoid rewriting same flash page multiple times
when writing subsequent flash pages. The cache is used for reads to
account for reading not yet committed (i.e. dirty) page data. Speeding
up reads is not intention of this patch and therefore the read path
does not modify cache state.
