spi: spi-imx: Fix pm_runtime_set_suspended() with runtime pm enabled
[ Upstream commit b6e05ba0844139dde138625906015c974c86aa93 ]
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.
