Adding Macronix Octal flash for Octal DTR support.

The octaflash series can be divided into the following types:

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.

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

MX66LM : 3.0V Octal I/O with stacked die
Link: https://www.mxic.com.tw/Lists/Datasheet/Attachments/8748/MX66LM1G45G,%203V,%201Gb,%20v1.1.pdf

MX66UM : 1.8V Octal I/O with stacked die
Link: https://www.mxic.com.tw/Lists/Datasheet/Attachments/8711/MX66UM1G45G,%201.8V,%201Gb,%20v1.1.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.
