Peter Korsgaard f1d1967422 board/ci20/genimage.cfg: drop hardcoded rootfs partition size 
As recently reported to the list:
http://lists.busybox.net/pipermail/buildroot/2020-January/271937.html

The hardcoded rootfs partition size can lead to hard to understand build
failures if more packages are added.

So drop the hardcoded partition size.  Genimage will then size the partition
to match the size of the rootfs image (which by default is also 60MB for ext4).

Introduction
============

The 'ci20_defconfig' will create a root filesystem and a kernel image
under the 'output/images/' directory. This document will try to explain how
to use them in order to run Buildroot in the MIPS Creator CI20 board.

How to build it
===============

Configure Buildroot
-------------------

  $ make ci20_defconfig

Build the rootfs
----------------

Note: you will need to have access to the network, since Buildroot will
download the packages' sources.

You may now build your rootfs with:

  $ make

(This may take a while, consider getting yourself a coffee ;-) )

How to write the SD card
========================

Once the build process is finished you will have an image called
"sdcard.img" in the output/images/ directory.

Make sure the SD card is not mounted then copy the bootable "sdcard.img" onto
it with "dd":

  $ sudo dd if=output/images/sdcard.img of=/dev/sdX

Insert the SDcard into your ci20, and power it up. Your new system
should come up now and start a console on the UART HEADER.
