Two platform-data fields for SM8750 were missed:

  - get_vpu_buffer_size = iris_vpu33_buf_size
    Without this, the driver fails to allocate the required internal
    buffers, leading to basic decode/encode failures during session
    bring-up.

  - max_core_mbps = ((7680 * 4320) / 256) * 60
    Without this capability exposed, capability checks are incomplete and
    v4l2-compliance for encoder fails.

Fixes: a5925a2ce077 ("media: iris: add VPU33 specific encoding buffer calculation")
Fixes: a6882431a138 ("media: iris: Add support for ENUM_FRAMESIZES/FRAMEINTERVALS for encoder")
