dmesg output can get very long, especially if debug messages are
compiled in and the maximum number of retained log messages is
increased.
Therefore, follow what we do for other potentially long-running
commands and allow the user to abort it with ctrl+c.

We already have pr_*_once, so duplicate it for dev_warn and friends as
well.

We do two allocations for each log message, one for the log message
string itself and another for the struct log_entry referencing it.
We could just make the log message directly follow the log entry and
save the space for the pointer and the time to do a second allocation.
No functional change.

The pointer is used no where, so let's save that space.

We have a number of APIs like regulator, clocks or reset, which return
an error pointer. To format that pointer for dev_err_probe, we need to
pass it through PTR_ERR(). Let's make such code more concise by defining
dev_errp_probe, which calls PTR_ERR() on its second argument.

dmesg open codes functionality to convert a string to a loglevel.
Make a separate function from it which will be useful in the next
patch.
While at it remove the BAREBOX_LOG_PRINT_* defines and use MSG_*
defines directly.

dev_WARN_ONCE() is like WARN_ONCE(), but with a struct device *argument
to print device context.

These are useful as a less verbose alternative to WARN_ONCE, which also
prints a stack trace if possible.

The '_d' suffix was originally introduced in case we want to import
Linux struct device as a separate struct into barebox. Over time it
became clear that this won't happen, instead barebox struct device_d
is basically the same as Linux struct device. Rename the struct name
accordingly to make porting Linux code easier.

This stores the probe deferral reason in the device structure.
If a probe is permanently deferred, the last reason is displayed.
Example output on a permanently deferred probe:
ERROR: imx-pgc-domain0: probe permanently deferred (Failed to get domain's regulator)
Other dev_err_probe outputs are displayed as before.

The function like it's Linux equivalent is meant to be used during
driver probe whenever an error occurs that would lead to aborting the
probe. This allows moving EPROBE_DEFER checks out of drivers and
in future could allow selectively compiling out only error probe
messages, as they are mainly interesting during bring up.

The point of <linux/printk.h> is to have a minimal self-contained header
for use where ever printing is required. va_list was used, but not
defined, remedy this.

Including <stdio.h> for printf is a bit problematic, because it pulls in
other headers for <console.h>, which includes quite a few more headers
as well. To make it easier to share code between barebox and host tools
make <printk.h> the new minimal header for printf and move the extra
logging stuff into <linux/printk.h>.
