[U-Boot] [PATCH] net: make net_random_ethaddr() more random

The net_random_ethaddr() tries to get some entropy from different startup times of a board. The seed is initialized with get_timer() which has only a granularity of milliseconds. We can do better if we use get_ticks() which returns the raw timer ticks. Using this we have a higher chance of getting
