coresight: cti: Add PM runtime call in enable_store
In commit 6746eae4bbad ("coresight: cti: Fix hang in cti_disable_hw()")
PM runtime calls are removed from cti_enable_hw/cti_disable_hw. When
enabling CTI by writing enable sysfs node, clock for accessing CTI
register won't be enabled. Device will crash due to register access
issue. Add PM runtime call in enable_store to fix this issue.
Fixes: 6746eae4bbad ("coresight: cti: Fix hang in cti_disable_hw()")
