[PATCH] integrate CFI Flash driver into mtd

[Sascha Hauer]

This is some general mtd cleanup and the integration of the CFI
Flash driver into mtd. Background is that current ubiformat
implementation relies on the mtd API.

First the mtd_read/write and friends we currently have are renamed
to libmtd_*, because they implement the functions from libmtd.
Then our internal mtd_read/write functions are renamed to mtd_op_*
because they implement the file_operations. Then we finally have
our namespace clean and can implement mtd_read/write as global
(kernel compatible) functions.
We currently miss the mtd_(un)lock functions needed for CFI
flash.
With this in place the final patch integrates the CFI driver into
mtd.
