From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx> Return the cached statistics in case the interface is down. There should be no drawback to this, as most of the statistics are updated on the data path and if runtime PM is enabled and the interface is down, the registers that are explicitly read on ravb_get_stats() are zero anyway on most of the IP variants. The commit prepares the code for the addition of runtime PM support.
