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 -https://www.mxic.com.tw/Lists/Datasheet/Attachments/7841/MX25LM51245G,%203V,...

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
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.

Other than this, the patch looks good to me.
MX66UW2G345G is similar to MX66UW2G345GX0 and MX66UW2G345G's device ID is 0xc2843c actually. So that I correct it and add MX66UW2G345GX0 in IDs table.
