[Intel-gfx] Getting primary plane_id in i-g-t

[Sagar Arun Kamble]

Including Ville in the thread.
I feel we need to update  following structure to reflect plane type.

struct drm_mode_get_plane {
        __u32 plane_id;

        __u32 crtc_id;
        __u32 fb_id;

        __u32 possible_crtcs;
        __u32 gamma_size;

        __u32 count_format_types;
        __u64 format_type_ptr;
};
