HiFive Unleashed A00 board has is25wp256d snor chip. It is observed that it gets configured with Serial Input Page program by the end of spi_nor_scan. Using the post bfpt fixup hook we prioritize the page program settings to use quad input page program (opcode:0x34) over serial input page program (opcode: 0x12). The patchset is tested on Linux 5.7.0-rc5. Changelog: =============================== V2: -Split common code between is25lp256 and is25wp256 devices as suggested Added a generic post bfpt fixup handler that identifies the flash parts based on their device id and uses the corresponding fixup. Other device's that need a post bfpt fixup can just add the device id check and either reuse the available fixups or write the necessary fixup code if one is not available. V1: -Moved SPI_SIFIVE from defconfig to Kconfig.socs for SOC_SIFIVE. Retained it's configurability using "imply" instead of "select" V0: Base version patch (Tested on 5.7.0-rc3).
