Miaoqian Lin d644e0d798 phy: mapphone-mdm6600: Fix PM error handling in phy_mdm6600_probe 
The pm_runtime_enable will increase power disable depth.
If the probe fails, we should use pm_runtime_disable() to balance
pm_runtime_enable(). And use pm_runtime_dont_use_autosuspend() to
undo pm_runtime_use_autosuspend()
In the PM Runtime docs:
    Drivers in ->remove() callback should undo the runtime PM changes done
    in ->probe(). Usually this means calling pm_runtime_disable(),
    pm_runtime_dont_use_autosuspend() etc.

We should do this in error handling.
