panfrost/mfbd: Include codes for float framebuffers

Browse source 
We see the hardware doesn't actually support float framebuffers in the
native sense -- rather, it just allows higher bpp framebuffers and lets
a blend shader / additional clear_color fields sort out the formats.
This will be.. interesting.
