drm/i915: Keep the AKSV details in intel_dp_hdcp_write_an_aksv()
Let's try to keep the details on the AKSV stuff concentrated
in one place. So move the control bit and +5 data size handling
there.
v2: Increase txbuf[] to include the payload which intel_dp_aux_xfer()
will still load into the registers even though the hardware
will ignore it
