mtd: rawnand: Check the data only read pattern only once
Instead of checking if a pattern is supported each time we need it,
let's create a bitfield that only the core would be allowed to fill at
startup time. The core and the individual drivers may then use it in
order to check what operation they should use. This bitfield is supposed
to grow over time.
