Changes since v1:
- Symlink raspberrypi3-64 and update BR2_ROOTFS_POST_[BUILD|IMAGE]_SCRIPT
- Add BR2_cortex_a53 architecture
- Set BR2_TARGET_ROOTFS_EXT2_BLOCKS to 120000
- Update kernel repository version

It looks good to me, but since Arnout had a look at the first version,
I'll wait for his review.
