We can use MEMSTICK_POWER_{ON,OFF} along with pm_runtime_{get,put}
helpers to let memstick host support runtime pm.
The rpm count may go down to zero before the memstick host powers on, so
the host can be runtime suspended.
So before doing card detection, increment the rpm count to avoid the
host gets runtime suspended. Balance the rpm count after card detection
is done.
