From: JaimeLiao <jaimeliao.tw at gmail.com>

Adding Macronix Octal flash for Octal DTR support.

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.

MX25LM : 3.0V Octal I/O

MX25UM : 1.8V Octal I/O
 -https://www.mxic.com.tw/Lists/Datasheet/Attachments/7525/MX25UM51245G%20Extreme%20Speed,%201.8V,%20512Mb,%20v1.0.pdf

MX66LM : 3.0V Octal I/O with stacked die
 -https://www.mxic.com.tw/Lists/Datasheet/Attachments/7929/MX66LM1G45G,%203V,%201Gb,%20v1.1.pdf

MX66UM : 1.8V Octal I/O with stacked die
 -https://www.mxic.com.tw/Lists/Datasheet/Attachments/7721/MX66UM1G45G,%201.8V,%201Gb,%20v1.1.pdf

MX25LW : 3.0V Octal I/O with Read-while-Write
MX25UW : 1.8V Octal I/O with Read-while-Write
MX66LW : 3.0V Octal I/O with Read-while-Write and stack die
MX66UW : 1.8V Octal I/O with Read-while-Write and stack die

MX25UM51245G : 512Mb flash, with Word mode data output format when Octal DTR read
MX25UM51345G : 512Mb flash, with Byte mode data output format when Octal DTR read

Macronix Octal flash with two types, "byte mode" and "word mode".
Because of word mode flash with byte swap issue when Octal DTR read,
adding byte mode flash in this patchset only.

About LW/UW series, please contact us freely if you have any
questions. For adding Octal NOR Flash IDs, we have validated
each Flash on plateform zynq-picozed.

As below are the SFDP table dump.
