The current Blackfin nand write function fills up the write buffer but
returns before it has had a chance to drain.  On faster systems, this
isn't a problem as the operation finishes before the ECC registers are
read, but on slower systems the ECC may be incomplete when the core tries
to read it.

So wait for the buffer to drain once we're done writing to it.

The current U-Boot UBI implementation is copied from Linux. In this
porting the UBI background thread was not handled correctly. Upon write
operations ubi_wl_flush() makes sure, that all queued operations, like
page-erase, are completed. But this is missing for read operations.

This patch now makes sure that such operations (like scrubbing upon
bit-flip errors) are not queued, but executed directly.
