kernel: backport GD25Q256 support from 4.15

Browse Source 
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":

Subject: [PATCH 1/2] mtd: spi-nor: add a quad_enable callback in struct
flash_info
Some manufacturers may use different bit to set QE on different
memories.
The GD25Q256 from GigaDevice is an example, which uses S6(bit 6
of the Status Register-1) to set QE, which is different with
other supported memories from GigaDevice that use S9(bit 1 of
the Status Register-2). This makes it is impossible to select
the quad enable method by distinguishing the MFR. This patch
introduce a quad_enable function which can be set per memory
in the flash_info list table.
