media: verisilicon: hantro: bound G2 HEVC tile loop to the buffer capacity
prepare_tile_info_buffer() writes one entry per tile into the tile_sizes
DMA buffer, sized for a grid equal to the PPS uAPI array capacity. Use the
bounded v4l2_hevc_pps_num_tile_columns() / v4l2_hevc_pps_num_tile_rows()
helpers so the loops stay inside the buffer.
