mtd: rawnand: timings: Add a helper to find the closest ONFI mode

Browse source

Vendors are allowed to provide their own set of timings. In this case,
we provide a way to derive the "closest" timing mode so that, if the
NAND controller does not support tweaking these parameters, it will be
able to configure itself anyway.
