mtd: rawnand: Create a legacy struct and move ->IO_ADDR_{R, W} there
We regularly have new NAND controller drivers that are making use of
fields/hooks that we want to get rid of but can't because of all the
legacy drivers that we might break if we do.
So, instead of removing those fields/hooks, let's move them to a
sub-struct which is clearly documented as deprecated.
We start with the ->IO_ADDR_{R,W] fields.
