[Buildroot] [git commit branch/next] olimex_a20_olinuxino_*: remove old SD writing instructions

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=a59dc492f0d7ddfc2d93b856a97288aece6b3c4c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Now that all the boards have been converted to use genimage, the old
instructions on how to partition and write an SD card are useless.
