This series suggests to isolate stacked/parallel support from spi-nor-core by moving that to SPI controllers and new modules under mtd/spi.
The patchset mainly focuses on removing references to stacked/parallel related items from core. The stacked/parallel support logic itself may have rooms to improve. Rework or further cleanup in stacked/parallel support would be done by other patches after this series is applied.
