Merge tag 'nand/for-7.2' into mtd/next

* Extend SPI NAND continuous read to Winbond devices, which requires
  numerous changes in the spi-{mem,nand} layers such as the need for a
  secondary read operation template.

* Continuous reads in general have also been enhanced/fixed for avoiding
  potential issues at probe time and at block boundaries.

Plus, there is the usual load of misc fixes and improvements.
