[GIT,PULL,v3] mtd: nand: Changes for 4.16

Hello,

Here is the NAND PR for 4.16. As can be seen in the diffstat, the NAND
subsystem has been quite active. That's mainly caused by the
introduction of the ->exec_op() hook and the rework of the Marvell
driver.

v3 contains 2 late fixes, and one of them is fixing a bug introduced by
the exec_op() rework, hence the need for a v3. Hopefully, this will be
the last version.

Regards,

Boris

Changes in v3:
- Fix a bug introduced by the exec_op() rework in the GPMI driver
- Fix a long standing bug in the sunxi driver

Changes in v2:
- Add a few fixes for the omap OneNAND and marvell NAND drivers
