Add support for using it in octal DTR mode. Try to verify the flash ID to check whether the flash memory in octal DTR mode and SPI mode are correct. When reading ID in OCTAL DTR mode, ID will appear in a repeated manner. ex: ID[0] = 0xc2, ID[1] = 0xc2, ID[2] = 0x94, ID[3] = 0x94... Rearrange the order so that the ID can pass. The octaflash series can be divided into the following types: MX25 series : Serial NOR Flash. MX66 series : Serial NOR Flash with stacked die.(Size larger than 1Gb) LM/UM series : Up to 250MHz clock frequency with both DTR/STR operation. LW/UW series : Support simultaneous Read-while-Write operation in multiple bank architecture. Read-while-write feature which means read data one bank while another bank is programing or erasing.

For adding Octal NOR Flash IDs, we have validated each Flash on plateform zynq-picozed.
