[PATCH v2 1/3] mtd: spi-nor: issi: is25wp256: Init flash based on SFDP

[Sudip Mukherjee]

The datasheet of is25wp256 says it supports SFDP. Get rid of the static
initialization of the flash parameters and init them when parsing SFDP.

Testing showed the flash using SPINOR_OP_READ_1_1_4_4B 0x6c,
SPINOR_OP_PP_4B 0x12 and SPINOR_OP_BE_4K_4B 0x21 before enabling SFDP.
After this patch, it parses the SFDP information and still uses the
same opcodes.
