mtd: spi-nor-core: Allow using Micron mt35xu512aba in Octal DTR mode
Since this flash doesn't have a Profile 1.0 table, the Octal DTR
capabilities are enabled in the post SFDP fixup, along with the 8D-8D-8D
fast read settings.
Enable Octal DTR mode with 20 dummy cycles to allow running at the
maximum supported frequency of 200Mhz.

Add support for various STMicro SPI flash chips (M25Pxxx and N25Qxxx)

+ help
+ Add support for the Micron MT35XU chip. This is a separate config
+ because the fixup hooks for this flash add extra size overhead. Boards
+ that don't use the flash can disable this to save space.
