This particular conditional was never driven by DT anyway; the original
code called machine_is_ventana() which I believe would have been
evaluated at compile time (and if not, the run-time evaluation wouldn't
have been DT-driven).

I imagine the code I modified here will be ripped out soon anyway; you'd
agreed to removing all the SPI/UART switching logic on Seaboard once the
LCD patches were in; we can all just set the jumper to "UART" mode
instead of "GPIO-controlled" then:-)
