interconnect: qcom: Make qnoc_remove return void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Several interconnect/qcom drivers use qnoc_remove() as remove callback.
Make this function return void (instead of unconditionally zero) and
adapt the drivers using this function accordingly.
