freedreno/a6xx: cl_khr_image2d_from_buffer support

Browse Source 
This allows sampling from a buffer as if it was a simple (single
level/layer, linear) 2d image/texture.  Add a helper to convert
struct pipe_image_view to an apprpriate fdl_layout and wire it up
in the image view and tex view paths.

Can be tested with cl cts:

 ./test_image_streams 2D read CL_RG CL_SIGNED_INT16 CL_FILTER_NEAREST CL_ADDRESS_CLAMP_TO_EDGE UNNORMALIZED

(for ex)
