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":

Newer batches of several Mikrotik boards contain this yet-unsupported
flash chip, for instance:
- rb941-2nd (hAP lite)
- rb952ui-5ac2nd (hAP ac lite)
- RBM33G
and probably other Mikrotik boards need this patch as well.
The patch was submitted upstream by Robert Marko: https://patchwork.ozlabs.org/patch/934181/
Closes: FS#1715

Some board vendors actually changed the loader to expect the chip
to come up in 4-address-mode and flipped the ADP bit in the flash
chip's configuration register which makes it come up in 4-address-mode.
Hence it doesn't make sense to avoid switching to 4-address-mode on
those boards but the opposite as otherwise reboot hangs eg. on the
WrtNode2 boards. Fix this by checking the ADP register and only using
SPI_NOR_4B_READ_OP on chips which have ADP==0 (come up in 3-byte mode).
See also datasheet section 7.1.11 Power Up Address Mode (ADP)
Fixes: 22d982ea0 ("ramips: add support for switching between 3-byte and 4-byte addressing on w25q256 flash")
