Z_LINK_ITERABLE_SUBALIGN for the subalignment instead of
a hardcoded value of 4.

usbh_req_desc() truncates the descriptor id. This problem is most
visible with string descriptor requests, as only then can wIndex be
greater than 0xFF. In particular, this affects commonly used language
IDs such as English (United States), which is 0x0409.

Do not enable subsystem/driver shell modules by default and stop abusing
CONFIG_SHELL_MINIMAL, which is internal to the shell subsystem, to decide
when to enable a driver shell.
The list of shell modules has grown considerably through the
years. Enabling CONFIG_SHELL for doing e.g. an interactive debug session
leads to a large number of shell modules also being enabled unless
explicitly disabled, which again leads to non-negligible increases in
RAM/ROM usage.
This commit attempts to establish a policy of subsystem/driver shell
modules being disabled by default, requiring the user/application to
explicitly enable only those needed.

Use the USB device structure and wrappers introduced earlier.
With this patch, users of ch9 requests do not need to work
directly with the UHC API. The requests are now blocked until
there is a response from the UHC. Callers finally have access
to the data buffer and request status.

Add a structure to represent a USB device and wrappers to avoid

road to device configuration and management, we can start with
the tools that can also be used for USB device support testing.

The current approach is a bit impractical in the upper layer.
This patch removes the two fifos that hold the transfer buffers
and replaces them with a byte array for the setup packet and
a pointer to a data buffer. The data buffer is mandatory for
all types of transfers except control without a data stage.
The waste of eight unused bytes for non-control transfers should
be insignificant, since an additional pointer would be at least
half of it, and then there would be the overhead of handling it.
This patch also clean up the transfer flags, rename owner to callback
as it reflects the upper layer use case, and add an additional member
to hold the pointer to the USB device (peripheral on the bus).

Until now iterable sections APIs have been part of the toolchain
(common) headers. They are not strictly related to a toolchain, they
just rely on linker providing support for sections. Most files relied on
indirect includes to access the API, now, it is included as needed.

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.
