board/olimex/a20_olinuxino: add linux-disable-lima.fragment
This Linux defconfig fragment is needed to disable Lima driver in favour of
Mali(if enabled). This because Lima is enabled by default in Linux's
sunxi_defconfig and if we enable Mali driver in Buildroot it will fail to
load. So let's set CONFIG_DRM_LIMA=n. Of course this fragment is only used
by Buildroot defconfigs that enable Mali driver.
