Benedikt Schmidt 3441fee460 drivers: spi: Implement workaround for unreliable busy flag
For some STM32 MCUs the busy flag of SPI is unreliable. This is a known
issue of the device and described in the device errata.
As a fix implement a configurable timeout which ensures that a call
to spi_transceive will eventually return.
Fixes #64927
