This fixes that u-boot gets stuck when a bitflip was detected
during "ubi part <ubi_device>". If a bitflip was detected UBI tries
to copy the PEB to a different place. This needs that the eba table
are initialized, but this was done after the wear levelling worker
detects the bitflip. So changes the initialisation of these two
tasks in u-boot.
This is a u-boot specific patch and not needed in the linux layer,
because due to commit 1b1f9a9d00447d
UBI: Ensure that "background thread" operations are really executed
we schedule these tasks in place and not as in linux after the inital
task which schedule this new task is finished.

This patch fixes a build problem noticed on Apollon by using
mtd_dev_by_eb() instead of "/" as done in the Linux UBI version.
So this brings the U-Boot UBI version more in sync with the Linux
version again.

UBI is quite memory greedy and requires at least approx. 512k of malloc
area. This patch adds a compile-time check, so that boards will not
build with less memory reserved for this area (CONFIG_SYS_MALLOC_LEN).

Return with correct error code (-ENOMEM) from ubi_attach_mtd_dev() upon
failing malloc().

With this patch now, the user can call "ubi part" multiple times to
re-connect the UBI device to another MTD partition.

This patch adds basic UBI (Unsorted Block Image) support to U-Boot.
It's based on the Linux UBI version and basically has a "OS"
translation wrapper that defines most Linux specific calls
(spin_lock() etc.) into no-ops. Some source code parts have been
uncommented by "#ifdef UBI_LINUX". This makes it easier to compare
this version with the Linux version and simplifies future UBI
ports/bug-fixes from the Linux version.
