media: v4l: Add definitions for HEVC stateless decoding
This introduces the required definitions for HEVC decoding support with stateless VPUs. The controls associated to the HEVC slice format provide the required meta-data for decoding slices extracted from the bitstream. They are not exported to the public V4L2 API since reworking this API will likely be needed for covering various use-cases and new hardware. Multi-slice decoding is exposed as a valid decoding mode to match current H.264 support but it is not yet implemented. The interface comes with the following limitations: * No custom quantization matrices (scaling lists); * Support for a single temporal layer only; * No slice entry point offsets support; * No conformance window support; * No VUI parameters support; * No support for SPS extensions: range, multilayer, 3d, scc, 4 bits; * No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.
