new make helper to decode binaries using base64 ...

This is helpful to provide mvebu binary.0 images with a patch. When
added directly a binary patch is needed which isn't understood by
patch(1).

As it's (at least) unclear if these images are distributable in general
I don't provide a patch making use of this, but the pattern is as
follows: Add

	$(obj)/start_netgear_rn2120.pblx.kwbimg: $(board)/netgear-rn2120/binary.0

to images/Makefile.mvebu and then put a binary.0.base64 into the board
folder.

sandbox: Fix registering file/fifo consoles ...

barebox_register_console() uses xzalloc which requires the malloc pool
to be initialized, so call it during the second option parsing when
this is already done.

sandbox: fix registering multiple consoles ...

Consoles need to be registered with the "console" device name so that
they are probed by the correct driver. The barebox_register_console()
was already forcing this as it was overwriting the name that was being
passed as argument, but it was failing to provide a unique id for
each new console, so the underlying register_device() would just
return an error when wanting to re-register a device with device name
"console" and id 0.

We remove the unused name parameter from barebox_register_console() as
it is really nowhere used, and also specify DEVICE_ID_DYNAMIC as id,
so that a new unique device id is given to each newly registered
console device.

cdev: make file operations const ...

scripts/checkpatch.pl warns that struct file_operations should be const,
but cdev->ops is not const, so without this patch we can choose between
a warning from checkpatch and a warning from the compiler about
discarding the const attribute when assigning the struct file_operations
cdev->ops.

Since there is no reason to modify the contents of cdev->ops after
probing, make it const.

I assumed all chipidea devices actually have a clock. This is true

use the clocks provided by the device tree. Most instead use
clkdev_add_physbase() to attach a clocks to devices. For these the
chipidea device does not have a clock.

commands: allow <cmd>_aliases[] to be const ...

Commands with aliases define an array of alias strings such as:

  static const char *<cmd>_aliases[] = { "<alias1>", NULL};

Although the elements are of type `const char *`, the elements
themselves are not `const`-qualified.  If the array is declared as:

  static const char * const <cmd>_aliases[] = { "<alias1>", NULL};

then the compiler warns about const qualifiers being discarded.  This is
because the `aliases` member of `struct command` is declared as `const
char *aliases;`.

Change the declaration of the `aliases` member of `struct command` to
`const char * const *aliases;` so that it can point to a `const` array
of `const char *`.  Also change the declaration of the `aliases`
variable in `register_command()` to avoid unnecessary type casts.
