Subject: [PATCH v2 0/1] mtd: spi-nor: gigadevice: gd25q256: replace gd25q256_default_init with gd25q256_post_bfpt

GD25Q256 'C' generation 'GD25Q256C' implements the JESD216 standards,
JESD216 doesn't define the QER field in BFPT, but the 'GD25Q256C'
does define QE bit in status register 1 bit 6, so we need to tweak
quad_enable to properly set the function.

'D' and 'E' generations implement the JESD216B standards, so parsing
the SFDP to set quad_enable function is enough for them.

As the default_init is deprecated, so the post_bfpt hook will be the
right place to do this tweak.

Changes since v1 [1]
 - Just tweak the quad_enable function when needed.
