drivers: flash: stm32 ospi: implement non busy wait polling

HAL_OSPI_AutoPolling is checking is the status match
happened in a busy loop. That CPU intensive operation
can cause starvation of other tasks especially on flash
erase operations which can take seconds to complete.

So, replace the use of HAL_OSPI_AutoPolling with
HAL_OSPI_AutoPolling_IT. The match results
HAL_OSPI_StatusMatchCallback being called.
