Ah right, I forgot about SPL debug. If we go for FDT based pinmux, we
have to init UART in some explicit way, as DT and SPL don't mix.

But even then I would like to get rid of the funcmux style and rather
let the boards provide a minimal UART pinmux init table, as funcmux
doesn't map too well onto the plethora of config options Tegra30
provides for the pinmux.
