For supporting AFBC: 1. Check if the user requested modifier can be supported by display HW. 2. Check the obj->size with AFBC's requirement. 3. Configure HW according to the modifier (afbc features) This patch depends on: - https://patchwork.freedesktop.org/series/59915/ - https://patchwork.freedesktop.org/series/59000/ v2: Rebase and addressed Ayan's comments Signed-off-by: James Qian Wang (Arm Technology China) <james.qian.wang@arm.com> Signed-off-by: Liviu Dudau <liviu.dudau@arm.com>
