[MTD] [NAND] make oobavail public
During the MTD rework the oobavail parameter of mtd_info structure has
become
private. This is not quite correct in terms of integrity and logic. If we
have
means to write to OOB area, then we'd like to know upfront how many bytes
out
of OOB are spare per page to be able to adapt to specific cases.
The patch inlined adds the public oobavail parameter.
