cdev_open() opens a cdev by name. This introduces cdev_do_open which
allows to open a cdev when the cdev is already found by other means.

currently most partition cdevs have the name <devname>.<partname>
This makes it hard to find a partition by <partname>. This introduces
a partname field in struct cdev so that.

To make that, we need to shift mtd_erase before mtd_ioctl.
ubi-utils need that, especially ubiformat.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

In the Kernel the mtd ioctls expect a pointer to the offset, whereas
barebox interprets the pointer itself as an offset. Since we want
to add 64bit support for file sizes a pointer may not be sufficient,
so align with the kernel and convert it to a pointer to the offset.

Support added for ioctl of ECCGETSTATS and MEMGETREGIONINFO.

For disk like devices attached to MCI, ATA or USB it depends on the order they
will be recognized. So an unique number for all disk like devices is required.

This makes it possible to compile without devfs. devfs_create/devfs_remove
is used by drivers and thus must still be present even without devfs support.
Also, this patch adds cdev_open/cdev_close/cdev_flush/cdev_ioctl calls to
work with devices without using the file api.
