Common code:-) :-) But ...

Not all Tegra30 will be Cardhu...

Given this is really board-specific, shouldn't the following be an empty
weak definition:

... and the function be overridden in board files as needed?

If we are moving to a model of a single function that sets up the entire
pin mux at boot (which seems fine to me, and could eventually be driven
by DT if it happened late enough), then it seems like we wouldn't need
e.g. pin_mux_mmc() or pin_mux_usb() any more.
