mtd: spi-nor: add DDR quad read support
This patch adds the DDR quad read support by the following:
[1] add SPI_NOR_DDR_QUAD read mode.
[2] add DDR Quad read opcodes:
SPINOR_OP_READ_1_4_4_D / SPINOR_OP_READ4_1_4_4_D
[3] add set_ddr_quad_mode() to initialize for the DDR quad read.
Currently it only works for Spansion NOR.
[4] set dummy with 6 for Spansion family
Test this patch for Spansion s25fl128s NOR flash.
