fix(spi-nand): add Quad Enable management
The framework currently supports QE feature only for Macronix devices.
Kioxia devices also support this feature, but this feature can not be
set based on the manufacturer ID as Kioxia first SPI NAND generation
does not support the QE feature when the second generation does.
Use a flag to manage QE feature. This flag will be added at board level
to manage the device.
