scsi: ufs: pltfrm: Drop PM runtime reference count after ufshcd_remove()
commit 1745dcdb7227102e16248a324c600b9121c8f6df upstream.
During the remove stage of glue drivers, some of them are incrementing the
reference count using pm_runtime_get_sync(), before removing the ufshcd
using ufshcd_remove(). But they are not dropping that reference count after
ufshcd_remove() to balance the refcount.
So drop the reference count by calling pm_runtime_put_noidle() after
ufshcd_remove(). Since the behavior is applicable to all glue drivers, move
the PM handling to ufshcd_pltfrm_remove().
