    mtd: spi-nor: allow dual/quad reads on S25FL129P
    
    According to the datasheet[1], both S25FL129P0 (256kB sectors) and
    S25FL129P1 (64kB sectors) support dual read, quad read, dual i/o read
    and quad i/o read.
    
    I have verified dual read to be working for S25FL129P1 on a dual
    capable spi controller. Quad as well as S25FL129P0 is untested, lacking
    hardware to verify.
