Subject: [PATCH 1/2] media: iris: Initialize HFI ops after firmware load in
 core init

The HFI command/response ops were previously initialized in probe(), but
we don't have firmware loaded at probe time. Since HFI is tightly
coupled to firmware, initialize the HFI ops after firmware has been
successfully loaded and booted.
