Shrinking vmlinux by disabling CONFIG_DRM allows the resulting FIT image
to meet the size constraint imposed by its flash partition.
CONFIG_DRM and CONFIG_DRM_ASPEED_GFX tend to be used for fbterm and
rendering the host console managed by uart-render-controller. For some
IBM platforms this is necessary, but not so much for Romulus. Disable it
to reduce the FIT image size so that it is not too large for its flash
partition.
For comparision, size(1) reports:
