Adding Macronix Octal flash for Octal DTR support.

The octaflash series can be divided into the following types:

MX25 series : Serial NOR Flash.
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.

MX25LW : 3.0V Octal I/O with Read-while-Write
MX25UW : 1.8V Octal I/O with Read-while-Write

MX25LM : 3.0V Octal I/O

MX25UM : 1.8V Octal I/O
Link: https://www.mxic.com.tw/Lists/Datasheet/Attachments/8967/MX25UM51245G,%201.8V,%20512Mb,%20v1.5.pdf

Those flash have been tested on Xilinx Zynq-picozed board using
MXIC SPI controller.
As below are debugfs data, the SFDP table and result of mtd-utils
tests dump.
