anv/cmd_buffer: Disable CCS on BDW input attachments

The description under RENDER_SURFACE_STATE::RedClearColor says,

   For Sampling Engine Multisampled Surfaces and Render Targets:
    Specifies the clear value for the red channel.
   For Other Surfaces:
    This field is ignored.

This means that the sampler on BDW doesn't support CCS.
