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

It is not the chip, but this controller which cannot do subpage writes.
So, make sure we add the flag at the proper place, so it doesn't get
overwritten by flash detection anymore.

autobooting does not work with little timeout and several attempts
have to be made until the network is finally up.

dev_add_child is a very unsafe function. If called multiple times
it allows setting the same device to different parents thus corrupting
the siblings list. This happens regularly since:

| automatically add it as parent of any bus device if none already specified

This patch fixes this by adding a device to its parents children list in
register_device so that dev_add_child is no longer needed. This function
is removed from the tree. Now callers of register_device have to clearly
set the parent *before* registering a device.

Currently we only support oldschool IDE SFF devices. This is done
by registering a register layout struct and everything else is done
by the generic IDE SFF driver. Since modern ATA devices still use
ATA, but not the SFF interface anymore, split out the IDE SFF support
to a separate file to allow for other types of ata interfaces.

Using /dev/disk* for every type of device is not helpful. It increases
the chance that the user doesn't know which file corresponds to which
device. So rename ata device files to /dev/ata*. Also add a dev_info
about which device just has been registered.

mtd->write is supposed to loop around pages internally, no need
to do this in mtd_write. This fixes a huge write performance drop
with the m25p80 driver when it was converted to a mtd driver recently.
Since mtd->writesize is 1 for this driver mtd_write ended up doing
single byte writes on the flash.

The nand layer handles partial page writes just fine. If the start or
end of the data is not page aligned, the nand layer will copy the data
to a temporary page buffer.
Remove the check which disallows partial page writes since this is what
we want to do on barebox when for example an image is written to nand
which is not padded to page size.

It could happen (1 out of 100 times) that NAND did not start up
correctly after warm rebooting, so barebox could not find its
environment or DMA timed out due to a stalled BCH. When resetting BCH
together with GPMI, the issue could not be observed anymore. We probably
need the consistent state already before sending commands to NAND.

When the built-in RTC in the i.MX28 is programmed to wake-up the SoC, the RTC
reports two events: RST and WAKE. RST is okay in this case, because the PMIC
was really powered down. But the real event is the WAKE from the RTC and
should have precedence over the RST event. So, report the WAKE event for this
special case.
