media: uapi: HEVC: Add num_delta_pocs_of_ref_rps_idx field

[ Upstream commit ae440c5da33cdb90a109f2df2a0360c67b3fab7e ]

Some drivers firmwares parse by themselves slice header and need
num_delta_pocs_of_ref_rps_idx value to parse slice header
short_term_ref_pic_set().
Use one of the 4 reserved bytes to store this value without
changing the v4l2_ctrl_hevc_decode_params structure size and padding.

This value also exist in DXVA API.
