This adds a translation layer to make the nrfx driver for the legacy (i.e. without EasyDMA) nRF SPI peripheral accessible via the updated Zephyr's API of the SPI driver. Configuration files are already prepared for adding support for SPIM (Master with EasyDMA) and SPIS (Slave with EasyDMA) peripherals. Signed-off-by: Andrzej Głąbek <andrzej.glabek@nordicsemi.no>

Enable support for nrfx SPI drivers for nRF MCU series.

Peripherals with the same instance ID cannot be used together,

e.g. SPI_0 and I2C_0. You may need to disable I2C_0 or I2C_1.
