Francois Ramu 081e2d5a54 drivers: spi: stm32 driver with dma checking spi busy status flag
Defines a function to control the spi busy state during DMA transfer.
After the DMA Tx, the spi might still have some data to Transmit.
The driver must wait for the SPI Tx before sending the next packet.
This is not required for the Rx part as the DMA Rx is already done.
Some mcus like stm32H7 have a TX complete bit, other must wait for the
TXE and BSY line.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.
