This series adds support for the spi_mem_poll_status() spinand
interface.
Some QSPI controllers allows to poll automatically memory
status during operations (erase or write). This allows to
offload the CPU for this task.
STM32 QSPI is supporting this feature, driver update are also
part of this series.
