kernel/4.{4, 9}: add manufacturer ID for Winbond NANDs

Some MikroTik devices are using a Winbond NAND flash. Linux treats
it as an unknown NAND before version 4.11:

  nand: device found, Manufacturer ID: 0xef, Chip ID: 0xf1
  nand: Unknown NAND 128MiB 3,3V 8-bit
  nand: 128 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 64

Backport a patch from 4.11 to show the manufacturer correctly:

  nand: device found, Manufacturer ID: 0xef, Chip ID: 0xf1
  nand: Winbond NAND 128MiB 3,3V 8-bit
  nand: 128 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 64

Tested on a MikroTik R951Ui-2HnD board.
