Hi!
this is an attempt to make OMAP2+ OneNAND driver DT aware.
Patches 1-5 could be probably omitted from later versions as their sole
purpose is to show code modifications which lead into patch 8.
Please take special attention to this patch as it is not yet finished.
We need latency and sync r/w mode to be returned from
gpmc_omap_onenand_set_sync_timings function, but I'm not happy with
any interface so far (return flags togerher with latency, return struct?).
Perhaps someone could come with different approach.
Also note that timings information from DT is not used at all, but needs
to be present, otherwise generic node probing code will bail out with
no timings. That's also worth fixing.
