Subject: [PATCH v5 03/10] media: venus: Refactor struct
 hfi_uncompressed_plane_info

This field is never used, but if we remove it we would change the size
of the struct and can lead to behavior change. Stay on the safe side by
replacing the single element array with a single element field.

This fixes the following cocci warning:
drivers/media/platform/qcom/venus/hfi_helper.h:1003:43-60: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
