net: make ARP timeout configurable
Currently the timeout waiting for an ARP reply is hard set to 5 seconds. On i.MX31ADS due to a hardware "strangeness" up to four first IP packets to the boards get lost, which typically are ARP replies. By configuring the timeout to a lower value we significantly improve the first network transfer time on this board. The timeout is specified in milliseconds, later internally it is converted to deciseconds, because it has to be converted to hardware ticks, and CFG_HZ ranges from 900 to 27000000 on different boards.
