[PATCH 0/3] mtd: rawnand: Sequential page reads

When reading sequential pages, the next page can be loaded in cache
without the need for a full new READ operation cycle. We can then
improve throughput a little bit in this case.

In order to support the feature we can split the series into two steps:
* make it possible to check if an operation is possible in advance
* check if sequential page reads (cache reads) are supported and if yes,
  use them on relevant operations rather than regular reads.

Controllers not leveraging the core's helpers might not benefit from
this addition.
