[MTD] driver model updates
Update driver model support in the MTD framework, so it fits
better into the current udev-based hotplug framework:
- Each mtd_info now has a device node. MTD drivers should set
the dev.parent field to point to the physical device, before
setting up partitions or otherwise declaring MTDs.
- Those device nodes always map to /sys/class/mtdX device nodes,
which no longer depend on MTD_CHARDEV.
- Those mtdX sysfs nodes have a "starter set" of attributes;
it's not yet sufficient to replace /proc/mtd.
- Enabling MTD_CHARDEV provides /sys/class/mtdXro/ nodes and the
/sys/class/mtd*/dev attributes (for udev, mdev, etc).
- Include a MODULE_ALIAS_CHARDEV_MAJOR macro. It'll work with
udev creating the /dev/mtd* nodes, not just a static rootfs.
So the sysfs structure is pretty much what you'd expect, except
that readonly chardev nodes are a bit quirky.
