[PATCH] media: hevc: Add sps_max_sub_layers_minus1 to v4l2_ctrl_hevc_sps

[John Cox <jc@xxxxxxxxxxxxx>]

sps_max_sub_layers_minus1 is needed if the driver wishes to determine
whether or not a frame might be used for reference.

Signed-off-by: John Cox <jc@xxxxxxxxxxxxx>

This is useful to the Pi H265 decoder as it allows it to only create
and store MV info for frames that need to.
