[RFC,00/34] mtd: spi-nor: Move manufacturer/SFDP code out of the core

Hello,

This patch series is an attempt at getting all manufacturer specific
quirks/code out of the core to make the core logic more readable and
thus ease maintainance.

This is just a preliminary version, and I'm pretty sure a lot of things
can be improved (Tudor already pointed some of them which I'll try to
address).

This series is split in 2:
- preparation patches (patches 1 to 11)
- the actual migration to one file per manufacturer + one file for the
  SFDP parsing logic

Feel free to comment on the approach.

Regards,

Boris
