if (ctx->dev->enc_capability & MTK_VENC_4K_CAPABILITY_ENABLE)
	fsize->stepwise = mtk_venc_4k_framesizes;
else
	fsize->stepwise = mtk_venc_hd_framesizes;

u8 h264_max_level;
if (ctx->dev->enc_capability & MTK_VENC_4K_CAPABILITY_ENABLE)
	h264_max_level = V4L2_MPEG_VIDEO_H264_LEVEL_5_1;
else
	h264_max_level = V4L2_MPEG_VIDEO_H264_LEVEL_4_2;

Patch V5 will be sent with these if there is no more comments.

This define is never used so it can be removed.
