spi: stm32: Update for OSPI and QSPI drivers

Browse source

Merge series from Patrice Chotard <patrice.chotard@foss.st.com>:

This serie applies the following updates on the spi-stm32-ospi and
spi-stm32-qspi dirvers :

  _ Update FIFO accesses using u16 and u32 when possible instead of u8
    only to optimize throughput.
  _ Replace Transmit Complete and Transmit Error interrupt management by
    usage of read_poll_timeout_atomic() to optimize throughtput.
  _ Simplify Status Match interrupt check.
  _ Set DMA burst configuration dynamically.
