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.

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.
