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.
