mtd: rawnand: Prevent sequential reads with on-die ECC engines

Browse source

commit a62c459795 upstream.

Some devices support sequential reads when using the on-die ECC engines,
some others do not. It is a bit hard to know which ones will break other
than experimentally, so in order to avoid such a difficult and painful
task, let's just pretend all devices should avoid using this
optimization when configured like this.
