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.

Add a genimage.cfg to create a working sdcard.img for the ci20
hardware. We also need a uboot-env.txt to create the partition for
the uboot environment.
Update the board/ci20/readme.txt with the related information. Remove
the tftp netboot description from the readme as it is already to
complicated for a basic bootable example.
