When a decoder instance is created, the W5_CMD_ERR_CONCEAL register
should be initialized to 0. Otherwise, gray color is occasionally
displayed on the screen while decoding.

Add support for runtime suspend/resume in the encoder and decoder. This is
achieved by saving the VPU state and powering it off while the VPU is idle.

Provide a control to toggle (0 = off / 1 = on), whether the SPS and
PPS are generated for every IDR.

Add initial support for the Wave515 multi-decoder IP. For now it is only
able to decode HEVC Main/Main10 profile videos into YUV420.
This was tested on FPGA prototype, so wave5_dt_ids[] was not expanded.
Users of the real hardware with Wave515 IP will have to
* provide firmware specific to their SoC
* add struct wave5_match_data like this:
static const struct wave5_match_data platform_name_wave515_data = {
.flags = WAVE5_IS_DEC,
.fw_name = "cnm/wave515_platform_name_fw.bin",
.sram_size = (71 * 1024),
};
* add item to wave5_dt_ids[] like this:
{
.compatible = "vendor,soc-wave515",
.data = &platform_name_wave515_data,
},
* describe new compatible in
Documentation/devicetree/bindings/media/cnm,wave521c.yaml

Move the excessive "sram-size" device-tree property to the device match
data. Also change the SRAM memory allocation strategy, instead of
allocating exactly sram_size bytes, allocate all available SRAM memory
up to sram_size. Add the placeholders wave5_vpu_dec_validate_sec_axi()
and wave5_vpu_enc_validate_sec_axi() to validate that the allocated SRAM
memory is sufficient to decode/encode bitstream with a given resolution.

Implement a separate setup routine for interrupts to reduce code
duplication. Also enable interrupts based on vpu_attr->support_encoders
and vpu_attr->support_decoders fields to facilitate support for other
Wave5xx IPs, because not all of them are both encoders and decoders.

Add the vpuapi layer of the wave5 codec driver.
This layer is used to configure the hardware according
