mdadm: drop auto= support

According to author (and what was described in man):
"With mdadm 3.0, device creation is normally left up to udev so this is
option is unlikely to be needed"
This was a workaround for kernel 2.6 family issues (partitionable and
non-partitionable arrays hell) and I believe we are far away from it now.

I'm not aware of any usage of it, hence it is removed.

-Instruct mdadm how to create the device file if needed, possibly allocating
-an unused minor number.  "md" causes a non-partitionable array
-to be used (though since Linux 2.6.28, these array devices are in fact
-partitionable).  "mdp", "part" or "p" causes a partitionable array (2.6 and
-later) to be used.  "yes" requires the named md device to have
-a 'standard' format, and the type and minor number will be determined
-from this.  With mdadm 3.0, device creation is normally left up to
-.I udev
-so this option is unlikely to be needed.

-For partitionable arrays,
-.I mdadm
-will create the device file for the whole array and for the first 4
-partitions.  A different number of partitions can be specified at the
-end of this option (e.g.
-.BR \-\-auto=p7 ).
-If the device name ends with a digit, the partition names add a 'p',
-and a number, e.g.
-.IR /dev/md/home1p3 .
-If there is no trailing digit, then the partition names just have a
-number added, e.g.
-.IR /dev/md/scratch3 .
-
-If the md device name is in a 'standard' format as described in DEVICE
-NAMES, then it will be created, if necessary, with the appropriate
-device number based on that name.  If the device name is not in one of these
-formats, then an unused device number will be allocated.  The device
-number will be considered unused if there is no active array for that
-number, and there is no entry in /dev for that number and with a
-non-standard name.  Names that are not in 'standard' format are only
-allowed in "/dev/md/".
