MLK-16075-12 gpu: imx: dpu: common: Add helpers dpu_vproc_has/get_fetcheco_cap()

This patch adds helpers dpu_vproc_has/get_fetcheco_cap() support
so that the users may check if a video processing mask has fetcheco
capability or get the fetcheco capability from the mask.
We currently only support fetcheco0 and fetcheco1.
