I'm going to send a v2 for this. Sorry for the noise

Since on olinuxino_lime/lime2 we have a Linux version >= 4.20 we need to pass drm_kms_helper.drm_leak_fbdev_smem=1 to kernel command-line that really enables DRM_FBDEV_LEAK_PHYS_SMEM. CONFIG_DRM_FBDEV_LEAK_PHYS_SMEM only adds the code for this, but drm_leak_fbdev_smem is 0 by default, so we need to override it. This fixes both olimex_a20_olinuxino_lime and lime2 that use extlinux.conf.
