pvr: Use the render passes' attachments array to setup ISP state

`pvr_setup_isp_faces_and_control()` can be called from a secondary
command buffer. The render pass info's `attachments` array is only
populated in the primary command buffer on which the render pass
was started, thus the `ds_aspect` being used always ended up being
`0` leading to incorrect ISP state being setup.

This commit changes the function to use the `attachments` array
from the render pass struct instead of the one from the recording
state.

dEQP tests fixed:
  dEQP-VK.renderpass.suballocation.attachment
    .{1.13, 1.65, 1.74, 3.219, 3.236, 3.314, 3.385, 4.426}
