ethernet: Add driver initialization priority to Kconfig

Browse source 
The default kernel init priority is too low. Make this
configurable and set the default priority so that the
ethernet driver is started just before the network stack.

This commit adds generic ethernet priority and changes
currently available ethernet drivers to use it.

Ethernet device driver initialization priority.
Do not mess with it unless you know what you are doing.
Note that the priority needs to be lower than the net stack
so that it can start before the networking sub-system.
