Giulio Benetti 220716ab67 configs/olimex_a20_olinuxino: fix mali not working because Linux version >= 4.20
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 with 1. Same goes for drm_fbdev_overalloc that
must be at least 200 for having a double buffer that is required by
Mali. This fixes both olimex_a20_olinuxino_lime and lime2 that use
extlinux.conf.
