spi: spi_qsd: Add Shared EE property check for spi

Add Shared EE property check for spi to support dual EE use case.
Have the prepare_message/unprepare_message API support for spi
for Dual EE use case so that client can have control for spi
driver get_sync, put_sync by calling the APIs pm_runtime_get_sync
and pm_runtime_put_sync_suspend and use them when switching to
other EEs. This will allow client driver to remove the delay/wait
time while switching between the secure and non-secure EEs.
