If a DSA switch driver cannot program an ageing time value due to it being out-of-range, switchdev will raise a stack trace before failing. To fix this, add ageing_time_min and ageing_time_max members to the dsa_switch in order for the switch drivers to optionally specify their supported ageing time limits. The DSA core will now check for provided ageing time limits and return -ERANGE from the switchdev prepare phase if the value is out-of-range.
