spi: spi-cadence: Fix pm_runtime_set_suspended() with runtime pm enabled
It is not valid to call pm_runtime_set_suspended() for devices
with runtime PM enabled because it returns -EAGAIN if it is enabled
already and working. So, call pm_runtime_disable() before to fix it.
Fixes: d36ccd9f7ea4 ("spi: cadence: Runtime pm adaptation")
