An 18-byte DTD with fixed reduced blanking (80 px / 45 lines — a virtual
display's blanking only has to be self-consistent), refusing modes the
encoding cannot carry (pixel clock past the u16 10 kHz field, 4K120-class;
>12-bit actives). Lives here rather than in the driver so it is unit-
tested on every platform; pf-vdisplay splices it over its hard-coded
1080p60 preferred-timing descriptor.
