UBI: provide LEB offset information
Provide the LEB offset information in the UBI device information data
structure. This piece of information is required by UBIFS to find out
what are the LEB offsets which are aligned to the max. write size.
If LEB offset not aligned to max. write size, then UBIFS has to take
this into account to write more optimally.
