spi: cadence-qspi: add system-wide suspend and resume callbacks
Each SPI controller is expected to call the spi_controller_suspend() and
spi_controller_resume() callbacks at system-wide suspend and resume.
It (1) handles the kthread worker for queued controllers and (2) marks
the controller as suspended to have spi_sync() fail while the
controller is unavailable.
Those two operations do not require the controller to be active, we do
not need to increment the runtime PM usage counter.
