[PATCH 3/5] media: iris: add AV1 decode buffer size support for vpu4x

[Wangao Wang]

Add necessary buffer size calculation to support AV1 decode for vpu4x

- wire AV1 into iris_vpu4x_dec_line_size() via hfi_buffer_line_av1d()
- add hfi_vpu4x_buffer_persist_av1d() for the vpu4x's persist buffer
  size calculation
- add BUF_PARTIAL to the vpu4x decoder dispatch table, which AV1D
  requires
