Using DEVICE_DEFINE, a device without a corresponding DT node can be
defined (for example CRYPTO_MTLS), Z_DEVICE_INIT() does not initialize
dt_meta for such devices, leaving the field as NULL.
device_get_dt_nodelabels() and functions calling it have to handle
dev->dt_meta == NULL to prevent fatal errors.

When getting gpio info for a specific device with no line
names, invalid memory was accessed.
The check for the length of the line name array has been
corrected to avoid this.

Use some new kernel features to make the experience of finding and
dealing with GPIO devices much more ergonomic by allowing the use of
devicetree node labels to identify GPIO devices by default.
Users who wish to avoid the associated footprint penalty can set
CONFIG_DEVICE_DT_METADATA=n by hand, but I think the convenience is
worth the price as a default. If we're running a shell, then we've
already paid a heavy footprint penalty.
Example output for qemu_cortex_m3:

Usage:
gpio toggle [device] [pin]
Also added Kconfig option so this command can be removed if
resources need to be conserved.

Use gpio toggle api instead of manually toggling.
Remove redundant text.
Print error and break from blinking if it occurs.
Only print 'how to exit' text if first toggle is successful.
Saves roughly 40 bytes.

Usage:
gpio info [device]
The new command prints gpio controller information
for a specific device if specified or if no device is specified
it prints out all controller information ordered by line name.
Also added Kconfig option so this command can be removed if
resources need to be conserved.

This commit implements this enhancement:
https://github.com/zephyrproject-rtos/zephyr/issues/63018
The forms of the gpio commands are now:
gpio conf device pin ol0
gpio set device pin 1
gpio get device pin
gpio blink device pin
Device name and pin subcommands now are
suggested/completed when tab is used.
Pin names are suggested with numbers and line names if
available from the gpio controller’s Devicetree node.
GPIO pin command is now limited to pins that are not assigned
as reserved.

The blink command should blink until the user presses a key, however on
some systems a pending keypress is present when entering the loop
causing it to immediate exit before getting a chance to blink.
Add a dummy read to clear the buffer before starting the blink loop.

We get compile warnings of the form:

Since isprint (and the other is* functions) return an int, change check
to an explicit test against the return value.

In order to bring consistency in-tree, migrate all drivers to the new

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver

No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.
