configs/ci20_defconfig: configure eth0 through BR2_SYSTEM_DHCP rather than kernel cmdline

Browse Source 
Passing ip=dhcp to the kernel will cause it to try to configure the network
interface using DHCP and wait up to 120s for the interface to detect a link,
slowing down boots without a network cable a lot.

Instead use the "normal" BR2_SYSTEM_DHCP, E.G.  trigger ifup to run the DHCP
client in the background.
