Subject: [PATCH] mtd: spi-nor: gigadevice: gd25q256: replace gd25q256_default_init with gd25q256_post_bfpt

From: Yaliang Wang <Yaliang.Wang@...driver.com>

When utilizing PARSE_SFDP to initialize the flash parameter, the
deprecated initializing method spi_nor_init_params_deprecated() and the
function spi_nor_manufacturer_init_params() within it will never be
executed, which results in the default_init hook function will also never
be executed. As we do have quad enable function defined in BFPT, the
post_bfpt hook will be the right place to tweak the function.
