lima: drop R16G16B16_FLOAT support

Browse source 
We're currently reporting support for this format, but trying to use it
leads to asserts in pan_access_tiled_image(). Right now, it's
effectively unused, because the state-tracker will end up using the RGBA
version, because that is renderable.

This is all about to change, so let's drop this format for now. But
because this is technically speaking supported on the HW, let's leave
this ifdeffed out with a comment to re-enable once the assert has been
fixed.
