    mtd: spi-nor: spansion: Use nor->addr_nbytes in octal DTR mode in RD_ANY_REG_OP
    
    [ Upstream commit b61c35e3404557779ec427c077f7a9f057bb053d ]
    
    In octal DTR mode, RD_ANY_REG_OP needs to use 4-byte address regardless
    of flash's internal address mode. Use nor->addr_nbytes which is set to 4
    during setup.
