mtd: spi-nor: gigadevice: gd25q256: Init flash based on SFDP
Get rid of the static initialization of the flash parameters and init them when parsing SFDP. Generated a 256 Kbyte random data and did an erase, write, read back and compare test. The flash uses for reads SPINOR_OP_READ_1_4_4_4B 0xec, for erases SPINOR_OP_BE_4K_4B 0x21, and for writes SPINOR_OP_PP_1_1_4_4B 0x34.
