kernel: backport GD25Q256 support from 4.15
Backport below changes for GigaDevice GD25Q256 support from v4.15:
e27072851bf7 mtd: spi-nor: add a quad_enable callback in struct flash_info
65153846b18c mtd: spi-nor: add support for GD25Q256
This chip is used on newer Quad-E4G boards.
Before:
[ 2.366493] m25p80 spi0.0: unrecognized JEDEC id bytes: c8, 40, 19
[ 2.372853] m25p80: probe of spi0.0 failed with error -2
After:
[ 2.371722] m25p80 spi0.0: gd25q256 (32768 Kbytes)
[ 2.376694] 5 fixed-partitions partitions found on MTD device spi0.0
[ 2.383043] Creating 5 MTD partitions on "spi0.0":
[ 2.387824] 0x000000000000-0x000000030000 : "u-boot"
[ 2.394138] 0x000000030000-0x000000031000 : "u-boot-env"
[ 2.400608] 0x000000031000-0x000000040000 : "config"
