This patch adds support for Octal SPI data reads in SPI NOR framework.
Opcodes for programming using octal interface are also present for the
sake of completeness, despite not being used.
Micron mt35xu512 flash is added as an example chip supporting that mode.
Signed-off-by: Artur Jedrysek
Device Tree is added to indicate such capability.
Both (revision and compatible) are used to determine, which mode to
pass to spi_nor_scan() call.

Changelog:
v2: Use new compatible in DT, instead of boolean property, to indicate
Octal SPI support.

Cadence Quad SPI driver successfully runs on Xtensa CPU, and Kconfig
file is updated to indicate that.
