spi: stm32: Update for OSPI and QSPI drivers
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.
