spi: rspi: Fix invalid SPI use during system suspend
If the SPI queue is running during system suspend, the system may lock
up.
Fix this by stopping/restarting the queue during system suspend/resume,
by calling spi_master_suspend()/spi_master_resume() from the PM
callbacks. In-kernel users will receive an -ESHUTDOWN error while
system suspend/resume is in progress.
Based on a patch for sh-msiof by Gaku Inami.
