We have dev_add_param_enum() now, so use it for the mode_name
setting. Also drop the special case for single mode framebuffers,
just add the mode_name parameter for this case aswell.

And use it inside struct fb_info. This struct has the advantage
that the supported modes can be passed around in a single pointer.

This updates the clk-divider to Kernel code, but without power-of-two
divider support which we do not need yet. This also adds table based
divider support to the divider.

If the ubidetach command is given a number that passes the range check
in ubi_detach_mtd_dev, but at which index the ubi_devices array contains
a NULL pointer, ubi_get_device tries to dereference this NULL pointer
to increment the ubi device reference count.

I am using an sam5d35 and its pmecc nand ecc controller.
In barebox, using similar atmel_nand.c the system crashes.
The problem was a call to chip->ecc.hwctl from nand_write_subpage_hwecc
(nand_base.c) when we write a sub page.
chip->ecc.hwctl function is not set when we are using PMECC controller.
As a workaround, i set NAND_NO_SUBPAGE_WRITE for PMECC controller in
order to disable sub page access in nand_write_page.
I think we can have the same problem in Linux. I do not performed
subpage nand writes from Linux but i made the following patch according
to my Barebox defect.

By default UBI is very verbose. Decrease the verbosity, turn
printf messages into ubi_ messages and add device parameters
for the values which are not printed anymore.

We need to setup the info->dev pointer before flash_get_size() since it
might use it for dev_dbg().
This fix a crash on boot when debug output is enabled.

struct ubi_device and struct ubi_volume have devices attached
to them. Register them to make them part of the barebox device
hierarchy.

So far mtd partitions were mtd devices, but these were not registered.
This patch changes this. mtd partitions are now registered like real
mtd devices. This makes them part of the device hierarchy.

struct mtd_info contains members which should not be copied
to the new partition, like for example the class_dev, so
only copy selected members of struct mtd_info to the partition.

mtd->parent is optional so we can't derefence mtd->parent->device_node
without checking mtd->parent.

erase_info may be modified by the mtd partition code, so
set the address each time we call mtd_erase.
