counter: ti-ecap-capture: Use devm_pm_runtime_enable()

Browse source 
There is no need to register a manual `devm` action for
`pm_runtime_disable()` when `devm_pm_runtime_enable()` exists. It does
the same thing (but also calls `pm_runtime_dont_use_autosuspend()`,
which should be fine here).

Moreover, when `devm_add_action_or_reset()` fails, it is due to a failed
memory allocation and will thus return `-ENOMEM`. `dev_err_probe()`
doesn't do anything when error is `-ENOMEM`. Therefore, the call to
`dev_err_probe()` is useless. Note that `devm_pm_runtime_enable()` has a
tail call to `devm_add_action_or_reset()` and thus returns that value.
Therefore, replace `dev_err_probe()` with the returning value.
