mtd: spinand: winbond: Enable high-speed modes on w25n0xjw
w25n0xjw chips have a high-speed capability hidden in a configuration
register. Once enabled, dual/quad SDR reads may be performed at a much
higher frequency.
Implement the new ->configure_chip() hook for this purpose and configure
the SR4 register accordingly.
