Merge tag 'nand/for-6.13' into mtd/next

SPI-NAND changes:
A load of fixes to Winbond manufacturer driver have been done, plus a
structure constification.

Raw NAND changes:
The GPMI driver has been improved on the power management side.
The Davinci driver has been cleaned up.
A leak in the Atmel driver plus some typos in the core have been fixed.
