[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=6ce681d2f69c5f0c2c3f581f8f5dda8822ede5bc
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.02.x

Libdrm freedreno depends on BR2_arm || BR2_aarch64 || BR2_aarch64_be
as such we need to propagate those dependencies to mesa's gallium
freedreno driver.
