Use devm_pm_runtime_set_active_enabled to replace
pm_runtime_set_active() + pm_runtime_enable() and drop the out_pm
error label and now-unnecessary remove function.

We still need the pm_runtime_get_sync() here since the driver uses
devm_get_clk_enabled() - we need to exit remove() with the clock
enabled. The other changes look OK.
