mmc: sunxi-mmc: Fix clock refcount imbalance during unbindmmc-v6.2-rc2
If the controller is suspended by runtime PM, the clock is already
disabled, so do not try to disable it again during removal. Use
pm_runtime_disable() to flush any pending runtime PM transitions.
Fixes: 9a8e1e8cc2c0 ("mmc: sunxi: Add runtime_pm support")
